Tony, all:
I went back to basics and used the following to build:
./swift/utils/build-script -R --xctest --foundation -t
Unfortunately I get the same result - missing symbols for enumerations in
libFoundation.so. Once again I'm building against the master branch for
all repositories.
I'm going to build the debug configuration now and see - I would be curious
to know if anyone can reproduce this, I'd be happy to write up a Dockerfile
or something to at least have someone confirm the reproducibility.
