Xorg log with backtrace

After compiling the latest mesa 19.1.0 version on Ubuntu 16.04 with libdrm 2.4.97 (or 2.4.98) and LLVM 8.0.1 Xorg segfaults at address 0x6d, using the radeonsi driver on AMD Radeon (TM) Pro WX 7100 Graphics (POLARIS10). The Xorg.0.log is attached.

[     4.187] (EE) 3: /opt/mesa-latest/x86_64/radeonsi_dri.so (0x7f5f52ac0000+0x1b9335) [0x7f5f52c79335]
[     4.187] (EE) 4: /usr/lib/x86_64-linux-gnu/dri/radeonsi_dri.so (0x7f5f4528c000+0x264dce) [0x7f5f454f0dce]

Looks like there's a mix between radeonsi_dri.so from Ubuntu packages and from AMD release packages. IIIRC this could happen when the former were upgraded after the latter were installed. Try re-installing the latter.

Thanks, looks like clearing up the mixed libraries fixed the issue.
