After following the execution that ends in the crash, I could not really understand what was going on around line 125 of cairo-polygon.c because the pointer "limits" goes from non zero to zero by passing the VALGRIND things line. So I checked options passed to configure/make/gcc and tried two things : * to force no use of -O with the -g -> the crash does not happen * to disable while -g and -O are in the CFLAGS -> the crash does not happen Ii may be that it should have been obvious to me from the start that debug+valgrind don'"t mix well with -O optimizations. Sorry for the noise. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

Hi, I don't how to start and if this is useful at all. On my ppc G4 gentoo, I have problem with cairo for month now since 1.10. At the beginning of may 2011, I tried with the git HEAD and it gave me back thunderbird and firefox. But then I had to upgrade for Qt upgrade to 4.8 but this brought crashes. So, I tried running tests to see what I could find. They give a lot of crashes, so many that I am not sure this report can be useful as it looks like I have a very cranky system (but KDE-4.6.5 is run quite fine on it). Some are assert failures, some are not. Launching : make run TOOL=gdb gives me a crash : #0 _cairo_polygon_limit (polygon=0xbfffc458, limits=0x0, num_limits=1) at cairo-polygon.c:93 #1 0x0ff0ef50 in _cairo_polygon_init (polygon=<optimized out>, limits=<optimized out>, num_limits=<optimized out>) at cairo-polygon.c:137 #2 0x0fefcab8 in _cairo_path_fixed_fill_to_traps (path=0x1015aef4, fill_rule=CAIRO_FILL_RULE_WINDING, tolerance=<optimized out>, traps=0xbfffc858) at cairo-path-fill.c:258 #3 0x0ff8a458 in base_compositor_fill (_compositor=<optimized out>, extents=0xbfffcb28, path=0x1015aef4, fill_rule=CAIRO_FILL_RULE_WINDING, tolerance=<optimized out>, antialias=<optimized out>) at test-base-compositor-surface.c:772 #4 0x0fedf96c in _cairo_compositor_fill (compositor=0xffb1c9c, surface=<optimized out>, op=<optimized out>, source=<optimized out>, path=0x1015aef4, fill_rule=CAIRO_FILL_RULE_WINDING, tolerance=0.10000000000000001, antialias=CAIRO_ANTIALIAS_DEFAULT, clip=<optimized out>) at cairo-compositor.c:167 #5 0x0ff282d8 in _cairo_surface_fill (surface=0x1015aae0, op=CAIRO_OPERATOR_OVER, source=0xbfffce58, path=0x1015aef4, fill_rule=CAIRO_FILL_RULE_WINDING, tolerance=0.10000000000000001, antialias=CAIRO_ANTIALIAS_DEFAULT, clip=0x0) at cairo-surface.c:1987 #6 0x0fee9234 in _cairo_gstate_fill (gstate=0x1015ad90, path=0x1015aef4) at cairo-gstate.c:1268 #7 0x0fed8630 in *INT_cairo_fill_preserve (cr=0x1015ac10) at cairo.c:2129 #8 0x1000bc04 in draw (cr=0x1015ac10, width=<optimized out>, height=<optimized out>) at a1-bug.c:47 #9 0x10008984 in cairo_test_for_target (ctx=0xbfffd134, target=0x10150754, dev_offset=<optimized out>, similar=<optimized out>) at cairo-test.c:920 #10 0x100099e4 in _cairo_test_context_run_for_target (ctx=0xbfffd134, target=0x10150754, similar=0, dev_offset=0) at cairo-test.c:1523 #11 0x1000b244 in _cairo_test_runner_draw (device_offset=<optimized out>, similar=0, target=<optimized out>, ctx=0xbfffd134, runner=<optimized out>) at cairo-test-runner.c:254 gcc is 4.5.3 By the way, how can I get an unoptimized-out test binary ? Thanks in advance.
