grsec - Denied RWX mmap of /usr/lib32/mesa/libGL.so.1.2.0

Team Fortress is crashing on linux-grsec. In the past, the only flag I had enabled for hl2_linux was "m" (disabled mprotect), but now I have to do "em" otherwise TF2 will crash the entire system.

[amarildo@amarildo ~]$ journalctl | grep /usr/lib32/mesa/libGL.so.1.2.0 Mar 25 14:36:30 amarildo kernel: grsec: denied RWX mmap of /usr/lib32/mesa/libGL.so.1.2.0 by /home/amarildo/.local/share/Steam/steamapps/common/Team Fortress 2/hl2_linux[hl2_linux:1902] uid/euid:1000/1000 gid/egid:100/100, parent /home/amarildo/.local/share/Steam/steamapps/common/Team Fortress 2/hl2.sh[hl2.sh:1899] uid/euid:1000/1000 gid/egid:100/100

Please fix this.
