Hello,

Does this make any difference?

yes, the emitted CFI helps libgcc's unwinder, preventing the segfault.
I should have looked at gcc -S output of signal_i386.c to see gcc's emitted CFI
of other functions ;-)

Maybe libgcc's unwinder just relied on the fact if there is any CFI present
(call_thread_func: .cfi_startproc and .cfi_endproc) it will be complete CFI.
Normally it would be the case if gcc's CFI generator produced the code.

The Wine packagers of Distros using gcc 4.4+ for building Wine 1.1.24 should be
notified to include your patch.

Regards
