State Changed From-To: open->analyzed Are you running bash from /usr/ports/shells/bash1 or /usr/ports/shells/bash2 or have you installed bash using some other mechanism? Please give more details of the exact version of bash you are running.

Yes, it looks like you're running bash2.04. The current version in
the Ports tree is 2.05 - I've just installed this version and the
showdate command fails with:
bash: return: bad non-numeric arg `Mon2001-Nov-19'
It looks to me like this problem is fixed now. Is it okay for me to
close this PR?

State Changed From-To: analyzed->feedback Please can you confirm whether the latest version of the bash2 port fixes this problem? If I don't hear from you soon, I'll assume that this isn't a problem with recent versions of FreeBSD as per my investigation.

If a shell function which is called by PROMPT_COMMAND returns a non-numeric value and generates an error message bush produces a core dump. Fix: :-( How-To-Repeat: put the following statements into a script test.bash: function showdate(){ return `date -j "+%a%Y-%b-%d"`; } showdate PROMPT_COMMAND=test_prompt_command.bash With the next prompt invocation the error message appears and the message about the core dump that is to be produced
