Actually, those are probably distinct issues, and it's not clear to me (yet)
whether the latter is a Valgrind issue.

Important context in the original output is the following:
wine: Unhandled illegal instruction at address 0x63bcd77 (thread 0150),
starting debugger...
Unhandled exception: illegal instruction in 32-bit code (0x063bcd77).
...
Backtrace:
...
0x063bcd77: repe
I.e., it looks to me like the issue is the repe/repz. Unfortunately I can't
tell from that output what instruction repe is supposed to apply to. I imagine
a dump of the affected code would be potentially useful, unless this bug report
is a duplicate of a known issue.
