Valgrind --malloc-fill=A5 --free-fill=DE crashes Wine

Hi,

I used to run Valgrind with the additional options
--malloc-fill=A5 --free-fill=DE
around Wine 1.2 times. Now I retried it and it crashes
Wine 1.3.13 and 1.3.14 (it fails to load kernel32.dll).

It turns out that malloc-fill is harmless, -free-fill causes havoc currently.

Am I the only one using or seeing this (Ubuntu Lucid)?

Thanks for your help,
 Jörg Höhle

It's most likely a valgrind/wine bug, does this patch work?

Cheers,

Works for me on Gentoo 32-bit.

Yes, that did the job with wine-1.3.12-14.
So is it a Valgrind or a Wine bug?

Thank you,
