Re: Cygwin/X just now started to crash with Solaris app, 8bpp UPDATE


Back with some more debug info.

GDB "settings"
break shadow.c:1290, 1295,1298
commands
silent
printf "PWB1/2/3 0x%x\n",*pScreen->PaintWindowBackground
cont
end
------------------------------------------------------------------------------------
Friday 22/10 17.35 CET
PWB1 0x78364c
PWB2 0x78364c
PWB3 0x4b987e
PWB1 0x78364c
PWB2 0x78364c
PWB3 0xff
!! Here it is, *pScreen->PaintWindowBackground get's fsck, i've tried forever to add a wathpoint in gdb so that gdb alerts me whenever it changes value and tells me what piece of code that does it.
However i've been unsucessfull, some pointers would be greatly appreciated.
(watch 'shadow.c'::*pScreen->PaintWindowBackground just doesn't work, gdb tells me "A parse error in expression, near `*pScreen->PaintWindowBackground'." although according to the gdb docs this should be allright ?
I've attatched the shadow.c that this debug output refers to.
Cheers,
