I tried to have a look at this problem yesterday evening, but I cannot
reproduce the segfault on linux/x86... "make test" fails because swscale
is doing some conversions in a different way respect to img_convert(),
but no segfaults.
Maybe the problem is windows dependent, or CPU dependent? I'll try to
steal a windows machine to someone, and to reproduce the segfault. Are
you using cygwin or mingw?
BTW, having EIP in in_asm_used_var_warning_killer() looks very wrong
(unless I am misunderstandig the code)... Maybe the stack frame is
corrupted and gdb output is unreliable?
Copy this in your signature, if you think it is important:
N O W A R ! ! !
