Re: [Tinycc-devel] Windows x86_64 BUG, SIGSEV is not correctly handled by installed signal handler.

Hi Michael,
Not only your patch lets the signal.c sample work on Windows x64/tcc -m64
but it also makes OpenLisp REPL happy on invalid code:

? (cons . 1)
** <program-error> : OpenLisp : machine-error : 11

Cherry on the cake, tcc is now promoted a Gold port :o))
There is no functional differences between VC++, gcc and now tcc.

Needleless to say I'm happy!

Thank you!

You can apply this patch to mod.

Thank you also to grischka for his help.

C.

So, with the hint of grischka I came up with the attached patch which
implements the plumbing in the startup files so that Christians example
signal.c works.  It's not in any way a real implementation of SEH, but that
isn't necessary.

I'll wait for feedback on this and not yet commit to git.


Ciao,
Michael.
