[M3devel] threading on Windows?

[Coleburn, Randy]

Jay:

I looked thru the 4,618 lines of M3x86.m3, but I don't see any reference to "m3_alloca" or even "alloc" in this file.

Regards,
Randy

In m3back/src/M3x86.m3.

I am certainly willing to work on the problem, but need more context info about what caused it in order to know how to resolve.
All I know is that everything was working fine until I checked out the HEAD repository.
When you say "special case" calls "m3_alloca", where do I go about finding this "special case"?
Are we talking Modula-3 code, C code, Assembler, what?  What package/module?

Randy

Maybe someone else can do it?
The fix is: special case calls to the function "m3_alloca".
Change it to call "_chkstk" (or maybe "chkstk", whatever works).
The one parameter is an unsigned 32bit quantity, passed in eax, and the return value is a pointer, returned in esp.
To some extent I drag my feet hoping anyone else might become motivated enough to do it and start learning how.
