I have rebuilt libxcb with !strip and CFLAGS="$CFLAGS -g". I have rebuild glibc
with !strip and CFLAGS="$CFLAGS -g" ...and... removed all the 'manual strip'
calls from the bottom of the package() function. The kdesktop crash happens just
as before, but now all the ? marks are gone from the backtrace. The new
backtrace with full information is:
http://www.3111skyline.com/dl/dt/trinity/arch/err/x86_64-archangel/kdesktop+libxcb+glibc-debug_03.kcrash
before removing the 'manual strip' info from package() it was:
http://www.3111skyline.com/dl/dt/trinity/arch/err/x86_64-archangel/kdesktop+libxcb+glibc-debug_02.kcrash
This is with Virtualbox 3.2.10. So I upgraded to 4.0.4 to see if there was any
change... There wasn't anything I noticed. Same kdesktop crash:
http://www.3111skyline.com/dl/dt/trinity/arch/err/x86_64-archangel/kdesktop+libxcb+glibc-debug_04.kcrash
I have no idea what the error means, but it looks like malloc is complaining
about corruption?
#8 0x00007f3550d27b96 in malloc_printerr (action=3, str=0x7f3550dd6a2e
"malloc(): memory corruption", ptr=<value optimized out>) at malloc.c:6283
#9 0x00007f3550d2a4ad in _int_malloc (av=0x7f3551012ea0, bytes=16) at malloc.c:4396
#10 0x00007f3550d2c460 in __libc_malloc (bytes=16) at malloc.c:3660
I'll also follow up with the Trinity folks because I have just tried downgrading
to glibc 2.13-3 and I'm still getting the error on x86_64. No issues with i686
though??
Any help pointing me in the right direction would be greatly appreciated :)
