I have narrowed the issue down to a reproducible case.
With Zsh 4.2.1 and 4.2.4, Zsh will hang when GDB runs the requested
command (i.e. /bin/ls). The execution runs as:
/usr/local/bin/zsh -c exec /bin/ls
Besides Zsh being the shell used, the shell needs to run a backtick
command in .zshenv. Example:
TESTING=3D`date`
I do not know why this only happens when called via GDB. Running the
command from the command-line returns without any obvious problems.
I was unable to reproduce this with /bin/tcsh or /bin/sh by adding the
above setting to .login (or .tcshrc) or .profile respectively.
With Linux, GDB and Zsh do not exhibit this problem, so I am unsure if
it is Zsh's or FreeBSD's bug.
