Problem

Unreal Tournament ('99) 32bit segfaults on some systems.

Systems

  • Lenovo P1 w/ Arch Linux (64bit)
    • mesa 19.1.1
    • multilib
  • QEMU VM w/ Arch Linux (64bit)
    • mesa 19.1.1
    • multilib
  • QEMU VM w/ Buildroot (32bit)
    • mesa 19.0.0
  • QEMU VM w/ Buildroot (32bit)
    • mesa 18.7.1

Behavior

Lenovo P1 w/ Arch Linux (64bit)

works perfectly

QEMU VM w/ Arch Linux (64bit)

QEMU VM w/ Buildroot (32bit)

mesa 19.0.0

mesa 18.7.1

works perfectly

Segfault

From what I can tell, the segfaults that are experienced are the same as those referenced in the following bug reports:

Notes

The buildroot mesa3d package build relies on autoconf. However, with 19.1.x upstream mesa has moved to meson for builds. Updating the buildroot mesa3d package to meson is non-trivial, and current attempts have failed. For this reason, building an Arch Linux environment was attempted. While the environment works, it behaves different from the Lenovo P1 install.
