bash 4.4 and BASHOPTS containing extdebug in env

This seems new for 4.4. Having extdebug in BASHOPTS seems to change the invocation behavior to mimic that of having specified the --debugger option, which I don't think is usually the intention: $ shopt -s extdebug; export BASHOPTS $ bash -c 'echo $BASH_VERSION; shopt -p extdebug' 4.3.42(1)-relea

Re: param expansion with single-character special vars in the environment

A related issue is with adding the nameref attribute to a readonly variable. Not sure if that should be allowed, as it can be used to change the meaning of the variable, even for variables that bash is using internally: $ TIMEFORMAT='%R' $ time bash -c 'readonly TMOUT=5; read'5.007 $ time bash -c

Unexpected exit

I came about this weird behavior when comparing some test cases I wrote for a little shell I made for a CS class. Here's the thing: $ echo | echo $(sleep 5) # ^Z and then bg to reproduce If you just let it run everything is fine, but the weird thing is when you stop it and resume in background ba
