Can you try compiling it without optimization, and then if it still
crashes try printing out the mask_image->component_alpha?
Also, try deleting this block in configure.ac:
support_for__thread=no
AC_MSG_CHECKING(for __thread)
AC_COMPILE_IFELSE([
__thread int x ;
int main () { return 0; }
], support_for__thread=yes)
if test $support_for__thread = yes; then
AC_DEFINE([TOOLCHAIN_SUPPORTS__THREAD],[],[Whether the tool chain
supports _
_thread])
fi
AC_MSG_RESULT($support_for__thread)
and then run autoreconf and configure again.
Finally, please keep the discussion on the list so that other people
can help out.
Thanks,
Soren
