Hello, I am suffering a crash im Thematic as soon as I open the image inspector of the theme. It happens on NetBSD/x86-32 with the gcc runtime. - I am unable to get the libobjc2 runtime working on NetBSD yet, so no comparison - on Linux, both 32bit and 64bit, gcc or libobjc2 runtime I do not have the issue nor does running valgrind show any useful result - valgrind is not available on NetBSD
I get this if compiled with -O2 Program received signal SIGSEGV, Segmentation fault. 0xae562bde in objc_msg_lookup () from /usr/lib/libobjc.so.4 (gdb) bt #0 0xae562bde in objc_msg_lookup () from /usr/lib/libobjc.so.4 #1 0x08055402 in -[ImagesView refreshCells] (self=<optimized out>, _cmd=0x8058f6f <-[ImageElement initWithView:owner:]+10162>) at ImageElement.m:354 #2 0xab02c110 in ?? () Backtrace stopped: previous frame inner to this frame (corrupt stack?) I compiled all GNUstep core in debug mode without -O2, but that doesn't help getting a better stacktrace, but no help. If I compile Thematic without -O2, I get no crash! Thus I suppose there is a memory error which gets hidden without optimization (addign lots of data can hide off-by one errors or such) and that it is in Thematic but not in gnustep base/gui. I tried compiling then -O1 and I think I finally obtain a useful stacktrace: Program received signal SIGSEGV, Segmentation fault. 0xacc13be4 in objc_msg_lookup () from /usr/lib/libobjc.so.4 (gdb) bt #0 0xb6cbdbe4 in objc_msg_lookup () from /usr/lib/libobjc.so.4 #1 0x08055467 in -[ImagesView refreshCells] (self=0x8054ef9 <-[ImagesView addObject:]+158>, _cmd=0xb3787290) at ImageElement.m:348 #2 0x08073248 in _OBJC_SELECTOR_TABLE () #3 0x08054ef9 in -[ImagesView addObject:] (self=0xb3787290, _cmd=0x8073330 <_OBJC_SELECTOR_TABLE+1136>, anObject=0xb2686100) at ImageElement.m:172 #4 0x08058fa1 in -[ImageElement initWithView:owner:] (self=<optimized out>, _cmd=0x806fc98 <_OBJC_SELECTOR_TABLE+1368>, aView=0xb380e410, aDocument=0xb28260f0) at ImageElement.m:544 #5 0x0804d5d3 in -[ThemeDocument elementForView:] (self=0xb28260f0, _cmd=0x806fbf0 <_OBJC_SELECTOR_TABLE+1200>, aView=0xb380e410) at ThemeDocument.m:472 #6 0x0804b86b in -[ThemeDocument changeSelection:at:] (self=0xb28260f0, _cmd=0x806fb60 <_OBJC_SELECTOR_TABLE+1056>, aView=0xb380e410, mousePoint=...) at ThemeDocument.m:316 #7 0x0804d113 in -[ThemeDocumentView mouseDown:] (self=0xb2731b70, _cmd=0xb7789150 <_OBJC_SELECTOR_TABLE+3568>, theEvent=0xb27e67d0) at ThemeDocument.m:207 #8 0xb753bf2f in -[NSWindow sendEvent:] (self=0xb26fba10, _cmd=0xb76b3cd0 <_OBJC_SELECTOR_TABLE+2448>, theEvent=0xb27e67d0) at NSWindow.m:4154 #9 0xb7334d22 in -[NSApplication sendEvent:] (self=0xb3710e10, _cmd=0xb76b3c08 <_OBJC_SELECTOR_TABLE+2248>, theEvent=0xb27e67d0) at NSApplication.m:2148 #10 0xb733336c in -[NSApplication run] (self=0xb3710e10, _cmd=0xb76a67c8 <_OBJC_SELECTOR_TABLE+936>) at NSApplication.m:1585 #11 0xb730f48d in NSApplicationMain (argc=argc@entry=1, argv=argv@entry=0xbfb336c8) at Functions.m:123 #12 0x0806592e in gnustep_base_user_main (argc=1, argv=0xbfb336c8) at main.m:31 #13 0xb6ef431f in main (argc=1, argv=0xbfb336c8, env=0xbfb336d0) at NSProcessInfo.m:1008 #14 0x0804a056 in ___start () #15 0x08049d87 in _start () I set NSZombieEnabled=YES but I get a crash anyway! usually that should save from such situations?
