Package: libc6
Version: 2.1.2-11
Severity: normal
Hi,
this bug occurs when I try to use bash completion in the following
context:
$ ls ~bonn<Tab>
Here is /etc/passwd:
[...]
+bonnaud::0:0:::
[EMAIL PROTECTED]::0:0:::
+:*:0:0:::/etc/NoShell
If I remove the line for the "info" netgroup, then bash does not crash.
$ export LD_LIBRARY_PATH=/usr/lib/debug
$ gdb bash
