bug#32943: grep pattern < fifo fails on Cygwin (and MinGW), but not on Linux

Old version? The version used by Cygwin is based on 3.0. As far as I can
tell, the most recent tarball is 3.1 ?????
Yes, that's the most recent release.
When building grep 3.1 for use with GDB, I suggest turning off optimization.
Something like this:
I did investigate using gdb and had a hard time getting a useful result
because of the indirection (grep . < fifo).
Try running grep as follows
$ gdb src/grep
(gdb) run . < fifo
#0 suppressible_error (errnum=22) at /usr/src/debug/grep-3.0-2/src/grep.c:595
That stack trace is coming from grep 3.0. Please debug grep 3.1 instead.
