I don't think the process running `cat' is a sibling of the subshell.
bash performs an optimisation that runs redirections applied to simple
commands that run external programs, or subshell compound commands after
the fork(). (to avoid having to restore file descriptors after running
the command.)
I think it's a good idea for the type builtin to distinguish between
static and loadable builtins, and for debugging scripts that use
loadable builtins, it would be useful to be able to see which file got
loaded. For example in cases where BASH_LOADABLES_PATH was
unintentionally unset or set to a w
To reproduce:
$ echo $BASH_VERSION
5.2.2(3)-release
$ ( : & wait ) > >(cat)
*hangs*
It should return immediately, but hangs instead.
if the argument is in the (-1, 0) range, the integer part is zero and
multiplying it by -1 has no effect, so the caller can't tell that the
argument was negative
