[BUG] clang-12: error: clang frontend command failed with exit code 139

[xloem]

Description

While building, the compiler crashed and informed me to report a bug. I have attached its generated data, which appears to likely form a test case.

clang.log
MaxUnpoolKernel_cpp_sh.tar.gz

Update: This crash went away for me when I switched to ndk 24-beta2.

• Host OS: Linux Ubuntu 20.04.3, running from docker image termux/package-builder

This need not be triaged for r24 as mentioned in the original report.

Crashes in r23 clang: SHA 8456c3a789285079ad35d146e487436b5a27b027
Fixed in r24 clang: SHA 0fe7531b75e54909a7cb7f7080634ab2053964ad

Next step is to identify a fix using git bisect and cherry-pick to the LTS compiler branch.

    [OPENMP]Fix PR48571: critical/master in outlined contexts cause crash.
    
    If emit inlined region for master/critical directives, no need to clear
    lambda/block context data, otherwise the variables cannot be found and
    it causes a crash at compile time.

https://android-review.googlesource.com/c/toolchain/llvm_android/+/1939337 cherry-picks it to the necessary branch. Just need a prebuilt update before r23c.

Whoops, a little overzealous while batch triaging :) Thanks

Should be fixed in r23 build 8486889.
