I had 4 crashes checking a large number of files for corruption using coreconverter.exe. I received messages indicating that I should post the dump files here. Three dump files are in the attached zip file. I have another dump file for a coreconverter.exe hang for over 30 minutes that I had to terminate in Task Manager after requesting a dump. It's 59MB and this forum refuses to permit me to upload it. Please let me know if there's any way to provide it. I'm more concerned about that one than the others because it blocked the calling Perl script until I happened to discover that the output file wasn't being updated. Thanks.
