Exception in wcstombs_sbcs

[Paul Vriens]

Hi,

when I run the latest Process Explorer (Version 9.0.3) I sometimes get
an exception:

fixme:ntdll:NtQuerySymbolicLinkObject (0x777e2ce4,0x777ebc28,0x12e4f878)
stub
wine: Unhandled exception (thread 000b), starting debugger...

The information above is from an older (Mar-01-05) version of wine but
CVS has the same problem.

Is there a way we can trace the stuff in libs/unicode ?

This exception occurs not every time (I guess 3 out of 5 runs) and the
only similarity is the exception is in wcstombs_sbcs.

Cheers,

Paul.
