Thanks, could you show me the output of the gdb command x/20hx lpSrc and x/s CreateAnsiFromWide(lpSrc)?

Here it is

Well, that's confusing. It seems like it should work, and that version works fine for me.

I'll think about what could have gone wrong.

Can you run these commands as well?

x/i $pc and i r

No hurry please :-)

That is really weird, it's using movaps which has alignment requirements, but then didn't align the stack.

esp+0x3c would be 0xffffbdf4, which is obviously not 16 byte aligned. I would have expected it to either force alignment of the structure, or used movups, which has no alignment requirement.

Is this an unusual compiler? Like, pre-release gcc or something? 😕

It's the standard 'gcc (Ubuntu 6.3.0-12ubuntu2) 6.3.0 20170406'. The make was fast and successful.

Ah-ha, I googled it a bit, someone else figured out the problem here:

I think his solution will work, I'll just add -mstackrealign to the Makefile.

Thanks for helping to debug this, that was unexpected!

I pulled it and ... you got it. Thanks a lot :-)
