Details

Description:
I just happened to check what changed in this slim version, and looked at the "fix-glibc*" patch;
The fact that one has to allocate one more cell in the child_env array is not due to glibc but to a context line that fortunately appears at the end of the patch file:
child_env[n] = NULL;
This explicitly writes beyond the end of the previously allocated array size (remember C/C++ arrays start counting at 0), thus a segfault in this case was perfectly legitimate and not a bug in glibc.

Additional info:
* package version(s)
slim 1.3.4-3
* config and/or log files etc.
in package build files: fix-glibc-segfault*.patch

Steps to reproduce:
n/a
This task depends upon
