It's strange that gdb shows free() being called during XtFree(ptr=0) since XtFree does nothing in this case. Maybe the stack arguments are messed up somehow, and ptr wasn't NULL in the beginning. Is this still an issue? If so, can you please try a build without optimizations (-O0) and reopen with a current backtrace. |

Bug reported by Sune Vuorela on the Debian BTS about 2 months ago. He gets a sigabort when trying to select some text in vim. > Program received signal SIGABRT, Aborted. > [Switching to Thread -1229543216 (LWP 18110)] > 0xb7f417f2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 > (gdb) bt > #0 0xb7f417f2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 > #1 0xb70e1d60 in raise () from /lib/i686/cmov/libc.so.6 > #2 0xb70e35b1 in abort () from /lib/i686/cmov/libc.so.6 > #3 0xb711808b in __libc_message () from /lib/i686/cmov/libc.so.6 > #4 0xb711feed in _int_free () from /lib/i686/cmov/libc.so.6 > #5 0xb7123530 in free () from /lib/i686/cmov/libc.so.6 > #6 0xb7628d31 in XtFree (ptr=0x0) at ../../src/Alloc.c:170 > #7 0xb764cf4b in GetConversion (ctx=0x82d72c8, event=0xbfd1f5c4, target=425, property=291, widget=0x82f6778) at ../../src/Selection.c:774 For some reason, GetConversion appears to be calling XtFree on a NULL pointer. It seems it could be related to the locale, maybe the lib doesn't support it. Locale: LANG=en_DK.ISO-8859-15, LC_CTYPE=en_DK.ISO-8859-15 (charmap=ISO-8859-15) Cheers, Brice
