Is this mean problem on just Ubuntu 14.04 - 32 bits gtk 2 ?
That means: any 32bit gtk2 application created by fpc compiler will
crash on any distro which realigns stack (eg sse2/sse3) inside
library.
Currently libpixman.so is critical (but tomorrow any C lib can be
critical), so such lib should be rebuilt with -mstackrealign passed to
gcc or fpc devels should make some magic to avoid such problem.Maybe
it will be good to open issue at fpc bugtracker about this.
second question if any application created other platform and
crosscompiled to linux 32bit, and this application has crash on
Ubuntu
14.04 - 32 bits gtk 2
Yes if we have above scenario. If you rebuild libpixman by yourself
(with -mstackrealign passed to gcc) then it won't crash.
There is already story about that problem:

Do you think it's useful to vote "affects me" in
https://bugs.launchpad.net/ubuntu/+source/pixman/+bug/1297845 [2] ?
Maybe. I don't use Ubuntu so don't know exactly how many votes can
trigger packager to take a look into problem. Someone should write there
that libpixman compiled with -mstackrealign fixes problem.
