Hello all,I'm observing a strange error: When a subshell spawned with command substitution uses a pipe, it crashes with a Stack Overflow. Hence, the following doesn't work: `var=$( echo hello world | cat - )` (More detailed reproducer attached.) I'm using GNU bash, version 4.4.19(3)-release (x86_64-pc-msys) on Windows 11. This bash is packaged by a company that provides it as part of their SDK. I'm already in contact with their support but am doing my own research in parallel. They currently seem unable to reproduce. Does this problem look familiar to someone? I hope it's a known problem that's fixed in a later version, so I could suggest a fix by upgrading the bash.
It's not a known or reproducible problem. I suspect it has something to do
with how msys simulates pipes on Windows.
