test-gtc_packing fails on i686 #212
Comments
Just as an additional note, the issue does not seem to affect either of clang 3.4 of Fedora 20 and clang 3.4.1 of Fedora rawhide. |
Hi, I think I fixed the issue but I could not reproduce the bug. Thanks, |
Damn, that bug is going to be a bummer. :/ |
Just a note that this issue is still present with GCC 4.9 as shipped in Fedora 21. The issue does not appear if the -ffloat-store option is passed to GCC. |
I finally figured the problem with this issue: Denorms! This issue is fixed in master and 0.9.8 branches for GLM 0.9.8.4 release. Thanks for reporting, |
Seems to happen with all 0.9.5* versions.
Steps to reproduce on GCC 4.8 on GNU/Linux, starting with PWD at the glm repository root
mkdir build
cd build
g++ -m32 -O2 -Wall -I .. ../test/gtc/gtc_packing.cpp
./a.out ; echo $?
The resulting test program exits with value 6, failing the test set.
So far, I have only had this happen on i686. Also it does not happen with -O1.
