Description:
Dear Maintainer,
I tried to collect some more information for the bug described in [1]
and could reproduce the crash just by repeating the given commands
in a minimal debian testing qemu VM. Backtrace in [2].
The last bash version where the crash did not manifest was bash_5.0-7.
In #972672 the last message mentions also wdequote_pathname and
wcsrtombs, therefore I guess this might be related.
As wcsrtombs[3] is specified to set under certain circumstances *src to
NULL,
I assume in this line [4] wpathname should not get dereferenced, or
at least just after being checked for a non-NULL value.
Kind regards,
Bernhard
