Package: bash
Version: 5.2.15-2+b7
Severity: normal
X-Debbugs-Cc: deb-b...@larsluthman.net
Dear Maintainer,
Bash crashed with SIGABRT after I typed a command ('git diff'). An
error message was printed but I did not have time to read it before
the terminal window tab that Bash was running in was closed, but I
think it is the one listed in the detailed backtrace below, in the
frame for malloc_printerr().
I have not been able to reproduce the bug but I have systemd-coredump
installed and I also installed bash-dbgsym to get more detailed
information. Here is the output of running 'bt' after launching gdb
using coredumpctl:
