Description Laszlo Ersek 2017-06-15 11:47:42 UTC

+++ This bug was initially created as a clone of Bug #1429050 +++

The exact same issue as described in bug 1429050 happens in RHEL-7.4 as well, using package "mesa-private-llvm-3.9.1-3.el7.aarch64".

Jeremy's patch in bug 1429050 comment 4 (direct link: attachment 1261680 [details]) applies to the above-mentioned RHEL-7.4 package (i.e., dist-git commit 6ec0b20b46c9) without conflicts, and works fine:

For RHEL-Alt-7.4, sibling bug 1461815 has been filed. For RHEL-7.5, please incorporate the patch normally.

Comment 2 Igor Gnatenko 2017-06-15 12:20:27 UTC

Please, can you create new bugs instead of cloning them? Me (and probably all others who were CCed on original bug) don't want to see RHEL-related bugs.

Comment 13 Miloš Prchlík 2018-01-22 13:23:55 UTC

The fix seems to be included in the sources, AFAICT after digging a bit into llvm srpm. I ran tests included in mesa-17.0.1-6.20170307.el7.src.rpm, no segfaults appeared. Switching to VERIFIED.

Comment 14 Miloš Prchlík 2018-01-22 13:24:44 UTC

Oh, and the llvm build tested was llvm-private-5.0.0-3.el7.
