** Description changed:
Binary package hint: zsh
I can reproduce crashing zsh when completing for "gsmc":
gsmc <tab>
Similar for "which gsmc".
This is the function, initially there was nothing commented out, but
I've tried narrowing it down, and came up with the commented lines to
trigger it:
gsmc() {
# [ x$1 = x ] && { echo "Commit update to which submodule?"; return 1;}
# [ -d "$1" ] || { echo "Submodule $1 not found."; return 2;}
# summary=$(git submodule summary "$1" 2>&1)
# if [[ $summary == "" ]] ; then
# echo "Submodule $1 not changed."; return 3
# fi
if [[ $summary =~ "^fatal:" ]] ; then
echo $summary ; return 4
fi
# summary=( ${(f)summary} )
git commit -m "Update submodule $1 ${${(ps:
:)summary[1]}[3]}."$'\n\n'"${(F)summary}" "$1"
}
- I can provide more information, in case the backtrace and this info
- alone is not useful enough.
+ Using `which` on it makes it hang before returning to the prompt:
+ % which gsmc
+ gsmc () {
+ if [[ "$summary" =~ "^fatal:" ]]
+ then
+ echo $summary
+ elif return 4
+ then
+ git commit -m "Update submodule $1 ${${(ps:
:)summary[1]}[3]}."$'\n\n'"${(F)summary}" "$1"
+ fi
+ }
+ *hangs here*

+
+ Attaching strace to it reveals nothing..

+ % sudo strace -f -p 13887
+ Process 13887 attached - interrupt to quit
