When i execute valgrind -v --leak-check=full --track-origins=yes glxinfo i get lots errors. Originally I got all the errors when testing an opengl coding project, but the errors also occur when running glxgears or glxinfo. I will attach the complete valgrind output. Reproducible: Always Steps to Reproduce: 1. install media-libs/mesa-10.2.4 or 10.2.5 x11-apps/mesa-progs-8.1.0 2. run valgrind glxinfo Actual Results: valgrind shows loads of memory errors. Expected Results: valgrind should be happy, no errors should be displayed.

Created attachment 382694 [details] the complete valgrind and glxinfo output
Please tell the upstream developers about this.
=> https://bugs.freedesktop.org/show_bug.cgi?id=82513
For the record: compiling libdrm while valgrind is installed fixes most of the errors. The libdrm configure script will detect valgrind's presence and enable all kinds of meminitialize fixes. This could be something to be integrated into portage: Triggering a rebuild for these packages XOR adding a valgrind use flag for libdrm.
