Using your tla-dos-1.3.1b.tar.bz2 I get a core dump.

Segmentation fault (core dumped)

$ ulimit

I do not see the core file, I'm pretty new to cygwin, so not sure how close it tries to be like unix/linux, but I thought with an unlimited ulimit I'd get a core file.

I think I *sort-of* was able to reproduce the problem. I managed to get a segmentation fault, but when I run it inside the debugger, I don't get a segfault. Which makes it seem like it is a timing thing. Having something to do with a child process.

Are you using a revision library or not? I almost always work with a greedy sparse revision library, placed at the root of one of my drives.

However, I'm still seeing random segfaults. I haven't figured out where it is segfaulting, but as near as I can tell, it seems to not see new files maybe 1% of the time. When this happens tla crashes.

Also, I wouldn't trust it until I get this sorted out. Because I'm also seeing random ++patches-missing-files.0 occurring.

And finally, I'm seeing a weird bug where the filename that is being accessed is "cev" instead of "dev" (basically it is always decrementing the first letter by 1). Probably there is a real bug in there, let me see if I can find it.
