Description Nikola Pajkovsky 2012-05-22 18:59:02 UTC

after calling rpmReadConfigFiles(NULL, NULL); valgrind yells 

==7516== Invalid read of size 1
==7516==    at 0x4C29162: __GI_strlen (mc_replace_strmem.c:391)

==7516==  Address 0x7fff52841d09 is not stack'd, malloc'd or (recently) free'd

all it starts in abrt-bodhi.c:330 which is line contains 

330 int status = rpmReadConfigFiles((const char *) NULL, (const char *) NULL);

I have slightly modified abrt-bodhi.c, but it's not related to rpm (tested w/o my changes) 

Version-Release number of selected component (if applicable):
rpm is taken from updates-testing repo

[npajkovs@f17-virt libreport]$ rpm -q rpm
rpm-4.9.1.3-7.fc17.x86_64

Comment 1 Panu Matilainen 2012-05-23 13:21:30 UTC

This is a valgrind anomaly (or false positive if you like) triggered by rpm now reading /proc/self/auxv, see https://bugs.kde.org/show_bug.cgi?id=253519
