I tried using bashdb for the first time. I was impressed with how well it
was working on a 32000 line ./configure script.
It had some trouble on line 23000 with a for loop. I created a simple
testcase that causes the problem to appear:
#!/bin/bash
for i in /bin /etc; do
echo $i
done
The script executes successfully without the debugger, but when the debugger
is used it gives the following output:
$ bashdb bashdb_test.sh
bash debugger, release 4.0-0.3

Debugged program terminated with code 1. Use q to quit or R to restart.
bashdb<1>
I'm using bashdb, release 4.0-0.3 on Fedora 11
I'm happy to assist with the debugging if there's anything I can help with.
Cheers,
Rob

Simple attempts to isolate the problem elude me so further research is needed. However I note if the debugger is installed and bash knows about it (i.e. has been compiled the right way) then this seems to work even though the banner comes out multiple times: $/bin/bash --debugger /tmp/bashdbbug.sh Shell Debugger, release Copyright 2002, 2003, 2004, 2006, 2007, 2008, 2009 Rocky Bernstein This is free software, covered by the GNU General Public License, and you are welcome to change it and/or distribute copies of it under certain conditions.

Ok. I think I have found and fixed the problem. Thanks for whittling it down to something manageable. (It was something really silly; surprising it wasn't detected earlier.) Please try out what's in git on sourceforge or the candidate release tarball http://bashdb.sourceforge.net/bashdb-4.0-0.4git.tar.bz2 There will probably be a general release soon.

Hi Rocky, That's great news! I've seen comments about complications with building bashdb correctly so I'll be a little explicit in what I tested: I cloned the git repo. Then ran ./autogen.sh and make. Then used "./bashdb -L . /tmp/bashdb_test.sh" to debug my script from within the top-level of my git clone. The testcase I provided passed without any problems. Originally the problem I saw used: "for i in $foo" with foo="/path" so I tested that too. That worked perfectly as well.
