Hi, there was already a bug report about this (bug 3528) but i now get a
different crash , so the issue still doesn't seem to be fixed.
After installation and trying to run Serious Sam the _first_ time i get:
wine: Unhandled page fault on read access to 0x54bbadc2 at address 0x54bbadc2
(thread 001e), starting debugger...
WineDbg starting on pid 0x3e
Unhandled exception: page fault on read access to 0x54bbadc2 in 32-bit code
(0x54bbadc2).
In 32 bit mode.

I don't know for sure that this is a bug in _vsnprintf.I've put a few extra
traces in it, and attach the output hereafter. Maybe someone who's familiar with
might see something suspicious

Note it runs fine with native msvcrt, and the bug is only present when i start
Serious Sam the first time.
