I tried to build current version of rust with coverage support.
Only different with current bc2504a version is #profiler = false --> profiler = True
build command is: RUST_BACKTRACE=1 ./x.py build
Out was:

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.
