Just thought I'd share an observation I found interesting.
Not a problem for me, so not asking for any particular response.
If I create a named pipe (mkfifo), as long as I write to and read from using
either 32-bit Cygwin or 64-bit Cygwin, all works fine, but if I write with either
one and read with the other, both processes hang.
It doesn't seem to matter whether the fifo was created under 32-bit or
64-bit, the problem (if I may be so bold as to call it that) seems only with
mixing 32-/64-bit versions doing I/O to/from it.
FWIW, using 32-bit version 1.7.29-2 and 64-bit version 1.7.30-1.
why do you expect such things to work ?
You have two separate simulation layers independent from each other.
Nothing is in place to pass the data from the 32 bit layer to the 64 layer.
