Dear Scientific Linux Developers, the SL6.2 gcc contains a fix for http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48597, an issue that made igprof crash under SL 6 for our users. For this fix to be fully effective, at least glibc needs to be build with the new gcc. I am not sure whether this has been done for SL6.2, so I want to make you aware of this requirement. Unfortunately this requirement is not explicit in the glibc SPEC file. Best regards, Matthias
