I am not sure if there will be another Clang 8 bug fix release. Does the issue also reproduce with a more recent version (e.g. Clang 10/Clang 11 release candidate/trunk)?

Thanks for responding.

I've git cloned the latest clang but the build fails on OpenBSD with :

    llvm-project/libcxxabi/../libcxx/include/__config:1150:6: error: "No thread API"

I can get past this with a modification to a #if, but then i get llvm-
project/build/include/c++/v1/locale:739:26: error: use of undeclared identifier
'strtoll_l'.

I'll ask openbsd.misc whether there's a set of patches that might get past
these issues.

In the meantime a workaround for the problem is to do "ulimit -d 4194304".

Julian,

Please try out a -current snapshot. -current was just upgraded from 8 to 10. Let us know if there was any improvement.
