Bug#883407: libc6: getpwnam_r() leaks memory

[Tim Rühsen <tim.ruehsen@gmx.de>]

Package: libc6
Version: 2.25-3
Severity: normal

Dear Maintainer,

valgrinding a C code shows the following:

==27943== 4,096 bytes in 1 blocks are definitely lost in loss record 3 of 3
==27943==    by 0x6C27715: getpwnam_r@@GLIBC_2.2.5 (getXXbyYY_r.c:314)
==27943==    by 0x4E8569F: rpl_glob (glob.c:781)

That rpl_glob() is gnulib's glob replacement. The code there looks good.
And valgrind doesn't/didn't show this leak with previous (2.24 and lower)
versions of glibc.

I can't currently provide you with a short reproducer (out of time here).

Regards, Tim
