OK, I have reproduced this on the FC9 system.
It looks like the memset call in sigemptyset is corrupting memory. I
have attached a patch which may be sufficient to work around the
segmentation fault in spawn but this is not sufficient overall. I
have a more thorough patch queued up that resolves this issue
entirely. I will check in those changes as soon as I can.
Sounds great! Do you think those changes will be available for the release?
I also found another, simpler, way of causing the error. Using a new
build (skipping over the errors from the libraries), just press C-c in
the repl. Then enter 0 to select the continue restart. You get a segv
at address 0.
Based on your patch and your comments, I think your full patch will be
needed to fix this.
