STR:
1. Build LLVM from SVN source code using the following script:
<a href="https://susepaste.org/c1b26468">https://susepaste.org/c1b26468</a>
2. Build ungoogled-chromium using this script:
<a href="https://susepaste.org/01f12c78">https://susepaste.org/01f12c78</a>
3. Execute the final binary /opt/ungoogled-chromium/chrome
EXPECTED:
The program should start normally.
ACTUAL:
An error message about "Illegal instruction" is displayed and the program
doesn't start.
[~]: /opt/ungoogled-chromium/chrome
Illegal instruction (core dumped)
[~]: [8940:8940:1120/151713.340872:ERROR:sandbox_linux.cc(379)]
InitializeSandbox() called with multiple threads in process gpu-process.
Using an older LLVM build (trunk 346299) which was also generated through step
1 does not give "Illegal instruction" and chrome works fine.
Additional note:
The second error about sandbox is unrelated to this bug and is displayed even
chrome is built with the good version of LLVM (trunk 346299). The first trunk
in which I noticed this problem was 346584. Reported also to
ungoogled-chromium:
