Unfortunately once one of these corrupted PCH files is created every compile fails, not just the first few. Also after the build is fully complete (failed) and I log into the build server and run the compiler by hand, I continue to get the failure every time with that PCH file. So, it's not just a temporary use of a partially-created file. I've checked the build logs and as far as I can see each precompiled header is built only one time, so it's also not a matter of the same PCH file being built multiple times and the commands stomping on each other. Thx for the note...
