Hi,
It looks like several bots assigned to you started failing after e6a39f00e8d0 was committed:
http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-armv8-linux-noe... http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-armv8-linux http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-aarch64-linux http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-aarch64-linux-n...
They all fail on the test libcxx/test/libcxx/modules/stds_include.sh.cpp with the following error:
<...>/libcxx/test/libcxx/modules/stds_include.sh.cpp:28:2: fatal error: file '<...>/libcxx/include/type_traits' has been modified since the module file '<TMP>/ModuleCache/1E92AHT/std-1V9DLRO.pcm' was built #include <vector> ^ <...>/libcxx/test/libcxx/modules/stds_include.sh.cpp:28:2: note: please rebuild precompiled header '<TMP>/ModuleCache/1E92AHT/std-1V9DLRO.pcm' 1 error generated.
Our other bots are not failing, so I very strongly suspect this is not because of the change itself, but rather some weirdness in your bot configuration. For that reason, I will *not* revert the change (that would likely not improve the situation anyway). Can you please collaborate with us to understand and fix the issue?
Thanks, Louis
