I compiled valgrind 3.1.0 with the above patch applied. I ran Icewind Dale II with valgrind '--trace-children=yes wine IWD2.exe'. It goes on for a short while outputting various errors until it freezes. It locks and I have to reboot the machine. I've tried to output it to a log as well, but the file is empty once I've rebooted, (perhaps the stream doesn't get flushed or whatever).
regarding IWD2: It may well be that this exhausts your memory, which in most cases brings the machine down to its knee
regarding the simple wine run: - the ld related errors are strange. I'm using ld-2.3.4 which doesn't show them. Likely a bug in ld-2.3.5 :-/ - the last errors are expected from vg 3.10 (I have the fixes if someone is interested, both for VG and some enhancements to wine)
and BTW, don't expect yet SEH in wine to work with vg A+
