22 years ago The following code snippet causes perl to die with an "unknown software exception (0xc0000029)" when trying to use sigtrap to catch "ctrl-C" at a DOS prompt.
#!perl use sigtrap 'handler'\, \&my_handler\, 'normal-signals';
while (\<>) { # minimal code to provoke bug! }
sub my_handler { local($sig = shift @_); print STDERR "Exiting after catching signal SIG$sig\n"; exit(0); }

however the same perl build (except for the fact it's ActiveState) in a DOS window bombs out. Anything in the handler is run (evidenced by printing something to stdout/stderr)\, as is "sub END" if it exists\, but then boom.
FYI cygwin is like unix (although it runs on windoze boxes) and is something completely different from win32. Cygwin builds perl with GNU C-compiler gcc and Win32 is build with M$ compiler
Your versions 5.6.1 says cygwin-multi (32 bit thread support)\, my 5.7.3 says cygwin-64int (64 bit no thread support). Both are very binary incompatible

Then it can probably be closed as "fixed in blead"?

cygwin does its own signal faking so is very different to native Win32. Bleadperl has different signal handling\, and in addition native Win32 has an attempt to fake more POSIX-like (rather than ANSI C required) functionality for signals (still not as good as it could be).

I run into a similiar problem (script using signals crashed at end of script) and was told back then "signals are totally unreliable under windows". Or something along these lines.
