Hello,
bash-4.4 doesn't build with --enable-static-link. Buidling with an
additional --without-bash-malloc makes it work.
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/libc.a(malloc.o):
In function `free':
(.text+0x5f20): multiple definition of `free'
Hello,
using bash-4.4, setting PS0 to '\[\033[1;36m\]started at
\t\[\033[0m\]\n' makes it output PS0 with a non-printable \x01\x02
prefix and suffix.

That sounds like a bad design for a log file anyhow. Log entries
should get flushed quickly, otherwise you lose the last few log
entries before a segfault or signal and have fewer clues about
the cause.

i've noticed
I ran into a problem using process substitution. A much reduced
version is
show below. The function f2 has the problem, the function f1 does
not. Are
there is some facts about the life cycle of the files created by
process substitution I don't appreciate? - ben

it was ^C'd (as you would
do when you realised you'd inadvertently catted or sedded a 3GB binary

There is an error on line 29 of variables.c in bash-3.1.
It should read:
#include sys/netmgr.h
not
#include sy/netmgr.h
Attached is a patch that fixes this, although it would be easier to
fix it manually.

P.S. Here is version information - it is possible that this feature
