this is wrong. every package is built with -g, however the debug symbols are
split out into separate -dbg or dbgsym packages.

is gdb using the split out debug symbols for your use case?

[Bug 1325503] Re: gdb reports 'corrupt stack' on armhf without symbols

[alamaral via ubuntu-bugs]

Don't know if anyone is still working on this problem (i.e. corrupt
stack on arm in gdb), but I've found a solution.  Any code that is
compiled with -g seems to work fine with gdb, as far as generating a
backtrace.  The problem is that most system library code is built
without -g, so gdb doesn't have whatever information is necessary to
unwind the stack properly.

It seems that gcc, with the -g option, adds .cfi directives into the
assembler code, and gdb needs that info.  Remove the .cfi directives and
you get the "Backtrace stopped: previous frame identical to this frame
(corrupt stack?)" error.

Even a very simple program with subroutine calls (similar to below) will
exhibit this problem:

void foo(int i)
{
if (i < 100) foo(i+1);
printf("i=%d\n", i);
}

main()
{
foo(0);
}

When compiled without -g each time the program calls foo the stack looks
to gdb like it's corrupted, and only the topmost level is shown, along
with the error.  Compile with -g and everything works, at least until
you step into printf, which wasn't compiled with -g.

Once you step out of printf you'll get your stack back.

This feels like a compiler bug to me, i.e. gcc __SHOULD__ generate at
least the minimal set of .cfi directives that are needed for gdb to
generate a backtrace, regardless of whether -g is specified or not.

Nonny Moose I have the same problem of you (running Ubuntu Mate and gdb

Actually I can't perform any application in debug due to the same segmentation

Did you solve the problem?

[Bug 1325503] Re: gdb reports 'corrupt stack' on armhf without symbols

[Brian Murray]

This may be partially resolved by the reintroduction of the patch in bug
1233185. The initial Stacktrace still ends in a corrupt stack but the
non-multiarch version of gdb is able to produce a more useful Stacktrace
and a StacktraceAddressSignature when retracing the crash.  For example,
with the gnome calculator crash from apport test crashes we can see the
following differences.

Stacktrace:
 #0  0x4081ed22 in poll () from /lib/arm-linux-gnueabihf/libc.so.6
 No symbol table info available.
 #1  0x4067c4e6 in ?? () from /lib/arm-linux-gnueabihf/libglib-2.0.so.0

If this is recommended, should it be turned on by default in gcc
upstream?

Barring that, should we turn it on by default in our gcc build in Ubuntu, or
in our common distro compiler flags?

[Bug 1325503] Re: gdb reports 'corrupt stack' on armhf without symbols

[Maxim Kuvyrkov]

How was "sleep" and system glibc compiled?

To get reliable stack traces GDB has to have access to either frame
pointer (-fno-omit-frame-pointer compiler flag) or to unwind tables
(-funwind-tables).  In the absence of either of these, GDB has to guess
where stack frame boundaries are.  In this case GDB guesses wrong.

The recommended way to get reliable stack traces is to use -funwind-
tables, which does not have performance penalty (like -fno-omit-frame-
pointer), and only increases disk footprint of binaries by several
percent.

So my team is telling me this defect is blocking the usefulness of the

you should be able to get these call stacks by using the dwarf debug

installed when trying to run crash?

[Brian Murray]

** Description changed:

- On armhf crash files fail to retrace and gdb reports 'corrupt stack'
- errors
+ [Test Case]
+ sleep 120 &
+ kill -SEGV %1
+ 
+ Observe a corrupt stack in the generated crash file.
+ 
+ Original Report
+ ---
+ On armhf crash files fail to retrace and gdb reports 'corrupt stack' errors
  
  For example bug 1323241
  Thread 1 (Thread 0xb0b3b450 (LWP 2243)):
  #0  0x0030 in ?? ()
  No symbol table info available.
  #1  0xa9990cbe in ?? () from 
/usr/lib/arm-linux-gnueabihf/unity8/qml/Unity/Launcher/libUnityLauncher-qml.so
  No symbol table info available.
  Backtrace stopped: previous frame identical to this frame (corrupt stack?)
  
  I also tried directly on the device to run an unstripped and stripped
  build of cat and gdb fails to unwind the stack when the binary is
  stripped. The result of this test is:
  
  == unstripped ==
  Reading symbols from ./cat...done.
  (gdb) run
  Starting program: /home/phablet/tmp/coreutils-8.21/src/cat
  ^C
  Program received signal SIGINT, Interrupt.

  (gdb) bt
  #0  0xb6f6e914 in read () from /lib/arm-linux-gnueabihf/libc.so.6

  #4  main (argc=1, argv=) at src/cat.c:730
  (gdb) quit
  
  == stripped ==
  Reading symbols from ./cat...(no debugging symbols found)...done.
  (gdb) run
  Starting program: /home/phablet/tmp/coreutils-8.21/src/cat
  ^C
  Program received signal SIGINT, Interrupt.
  0xb6f6e914 in read () from /lib/arm-linux-gnueabihf/libc.so.6

  #1  0xb648 in ?? ()
  Backtrace stopped: previous frame identical to this frame (corrupt stack?)
  
  I'd expect the same number of frames and addresses when the binary is
  stripped or not with '??' instead of names when it is stripped.

I built coreutils on utopic with DEB_BUILD_OPTIONS=nocheck,nostrip and
did receive a good stacktrace from gdb.

[Bug 1325503] Re: gdb reports 'corrupt stack' on armhf without symbols

[Brian Murray]

I installed the precise version of gdb (there was no gdb-minimal) on a
utopic system and that also ended in a corrupt stack.

[Brian Murray]

I install the saucy version of gdb-minimal 7.6.1-0ubuntu3 on a utopic
system and had the same corrupt stack.

[Bug 1325503] Re: gdb reports 'corrupt stack' on armhf without symbols

[Brian Murray]

I installed the trusty version of gdb 7.7-0ubuntu3.1 on a utopic system
with the same results. A binary that had strip run against it results in
a corrupt stack.

This is true with both gdb and gdb-minimal versions 7.7.1-0ubuntu3 in
utopic.
