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.
