Package: bash
Version: 3.1dfsg-8
Severity: normal
The following results in a segfault:
$ bash
$ $[/<tab>
In other words, first start a subprocess (to make sure the terminal does
not close when bash segfaults). After that, type '$', '[', '/', and
finally a tab to trigger the segfault.
[ This has been around for a number of years so I figured it would be
about time it was reported. There may be some other sequences, but this
is the shortest one I remember :-) ]
