[compiler-rt] r360914 - [libFuzzer] Disable merge-sigusr.test on linux.

[Yvan Roux via llvm-commits]

Hi Matt,

Thanks for the fix, unfortunately the flakiness is still here :(
Here are the last logs:

http://lab.llvm.org:8011/builders/clang-cmake-aarch64-lld/builds/6603/steps/ninja%20check%201/logs/FAIL%3A%20libFuzzer%3A%3A%20fork-sigusr.test

Thanks
Yvan
