Thanks for testing.
I've encountered a crash that might be related. I had previously been having
occasional crashes/hangs of cat.exe over the years, but this is the first time
I've ever gotten an error message:
cygwin error: 0 [fifo_reader] cat 11398 C:\cygwin\bin\cat.exe: *** fatal error
- Can't add a client handler, Win32 error 123
This isn't a crash in the usual sense. It's the Cygwin fifo code issuing a
fatal error because an attempt to create a new Windows pipe instance failed.
And it's in code that's been around for a while, so it's not related to the new
pipe implementation.
cat here is reading from a fifo created with mkfifo.
I've only encountered it once (out of daily runs over the last couple weeks) and don't
know how to replicate it. Possibly a race? Looks like my script has tried to
mitigate this with a sleep 1 between the mkfifo and the fork: cat < $fifo &
The sleep shouldn't be necessary. If it is, there's a bug in the fifo code.
Can you remove the sleep and see what happens? It would be great if that made
it possible to replicate the problem.
