[Ubuntu-x-swat] [Bug 756237] Re: wxRuby crashes with segmentation fault in pixman_image_composite32
I am also severely affected by this bug in Natty and desperately looking at least for a workaround. Below there is a stack trace of my simple gtk-application crashing in pixman_image_composite32() - I'm not sure if that helps.

[Ubuntu-x-swat] [Bug 756237] Re: wxRuby crashes with segmentation fault in pixman_image_composite32
I can confirm David Beswick's findings and add a few details.
I experience this bug with versions 0.20.2, 0.22.0 and 0.23.1 (from today's git
master). Please have a look at my attached gdb trace (pixman git master on
Ubuntu 11.04 x86_64, all optimizations disabled (./configure --disable-openmp
--disable-mmx --disable-sse2 --disable-vmx --disable-arm-simd
--disable-arm-neon CFLAGS='-g -O0')).
The interesting parts are:
[...]
#0 0x7fffea9b64d3 in lookup_composite_function (op=PIXMAN_OP_SRC,
src=0xf93b80, mask=0x0, dest=0xf93fb0, src_x=0, src_y=0, mask_x=0, mask_y=0,
dest_x=0, dest_y=0, width=8, height=1) at ../../pixman/pixman.c:378
info = 0x8
[...]
rax0x88
[...]
= 0x7fffea9b64d3 pixman_image_composite32+883:mov(%rax),%eax
The corresponding part in pixman/pixman.c:378 is:
369 for (i = 0; i N_CACHED_FAST_PATHS; ++i)
{
const pixman_fast_path_t *info = (cache-cache[i].fast_path);
/* Note that we check for equality here, not whether
* the cached fast path matches. This is to prevent
* us from selecting an overly general fast path
* when a more specific one would work.
*/
378if (info-op == op
info-src_format == src_format
info-mask_format == mask_format
info-dest_format == dest_format
info-src_flags == src_flags
info-mask_flags == mask_flags
info-dest_flags == dest_flags
info-func)
{
*out_imp = cache-cache[i].imp;
*out_func = cache-cache[i].fast_path.func;
goto update_cache;
}
392 }
So in line 378 pixman tries to read from a bad pointer.
When I comment that code part, everything seems fine.

I re-tested this in Natty and it still happened. But going off the suggestion in that bug, I recompiled wxruby while excluding GLCanvas, and I found the problem doesn't occur, wxruby works fine.

[Ubuntu-x-swat] [Bug 756237] Re: wxRuby crashes with segmentation fault in pixman_image_composite32
I've found out what causes this bug; I found this bug not in wxRuby, but in wxLua---but its the same bug, using pixman 0.20.0 seems to fix it. The offending commit (after trying each commit from 0.20.0 to 0.20.2 is: http://cgit.freedesktop.org/pixman/commit/?h=0.20id=6718621c62ef03d1dd71c34242a873aba798e8aa Yes, its a fix that broke it :P. After going through what it does, it basically enables support for __thread if the compiler supports it, and in this case gcc *does* support it. However, it looks like there's either a bug with the gcc __thread implementation, or how pixman uses __thread. Previously, such functionality looks like it would have defaulted to a pthread implementation. Looks like this needs to be pushed upstream (somewhere), because the same bug exists up to the current HEAD and disabling __thread support fixes it. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to pixman in Ubuntu. https://bugs.launchpad.net/bugs/756237 Title: wxRuby crashes with segmentation fault in pixman_image_composite32 ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 756237] Re: wxRuby crashes with segmentation fault in pixman_image_composite32
** Description changed:
+ Edited: I corrected the repro steps, thanks Marvin
+
This is a strange one, I'm not sure exactly where the fault lies.
Basically, performing almost any operation in a wxRuby app causes a
crash in pixman_image_composite32. This crash doesn't occur when running
regular wxWidgets apps or wxPython apps. The problem occurs on both ruby
1.8 and 1.9.1. It also occurs across all versions of wxRuby. The bug
doesn't show up on all linux distos (success has been reported with Arch
linux) but I think that's determined by the version of pixman that the
distro is using.
To repro:
1. Install ruby 1.9.1: sudo apt-get install ruby1.9.1
- 2. Install the wxWidgets gem: sudo gem1.9.1 install wxruby
- 3. Run the wxRuby bigdemo sample: ruby1.9.1
/var/lib/gems/1.9.1/gems/wxruby-2.0.0-x86_64-linux/samples/bigdemo/bigdemo.rb
+ 2. Install the wxWidgets gem: sudo gem1.9.1 install wxruby-ruby19
+ 3. Run the wxRuby bigdemo sample: ruby1.9.1
/var/lib/gems/1.9.1/gems/wxruby-ruby19-2.0.0-x86_64-linux/samples/bigdemo/bigdemo.rb
4. A segmentation fault occurs.
-
I've got wxRuby working by disabling some code in pixman. In the file
pixman/pixman.c, function lookup_composite_function, I
ifdef-ed out the following code:
- for (i = 0; i N_CACHED_FAST_PATHS; ++i)
- {
- const pixman_fast_path_t *info = (cache-cache[i].fast_path);
+ for (i = 0; i N_CACHED_FAST_PATHS; ++i)
+ {
+ const pixman_fast_path_t *info = (cache-cache[i].fast_path);
- /* Note that we check for equality here, not whether
- * the cached fast path matches. This is to prevent
- * us from selecting an overly general fast path
- * when a more specific one would work.
- */
- if (info-op == op
- info-src_format == src_format
- info-mask_format == mask_format
- info-dest_format == dest_format
- info-src_flags == src_flags
- info-mask_flags == mask_flags
- info-dest_flags == dest_flags
- info-func)
- {
- *out_imp = cache-cache[i].imp;
- *out_func = cache-cache[i].fast_path.func;
+ /* Note that we check for equality here, not whether
+ * the cached fast path matches. This is to prevent
+ * us from selecting an overly general fast path
+ * when a more specific one would work.
+ */
+ if (info-op == op
+ info-src_format == src_format
+ info-mask_format == mask_format
+ info-dest_format == dest_format
+ info-src_flags == src_flags
+ info-mask_flags == mask_flags
+ info-dest_flags == dest_flags
+ info-func)
+ {
+ *out_imp = cache-cache[i].imp;
+ *out_func = cache-cache[i].fast_path.func;
- goto update_cache;
- }
+ goto update_cache;
+ }
}
The bug doesn't occur after this modified version of pixman has been
installed. As far as I can see, the cache-cache[i].fast_path.func
pointer is pointing to an invalid location. I think the usual target of
these pointers is the following variable in pixman.c:
PIXMAN_DEFINE_THREAD_LOCAL (cache_t, fast_path_cache);
This thread local variable seems to be uninitialized or filled with
garbage when the crash occurs.
