The component on this bug should probably be switched back off of 'target' to
'libstdc++' as the broken stamps implementation is likely just latent on other
targets because none of them have filesystems with

Maybe I'm just thick, but from the generated
x86_64-apple-darwin17.0.0/libstdc++-v3/include/Makefile, it is entirely unclear
to me how the stamp mechanism and the current install-headers insures that

Thank you Jack, gcc-7.2.0 now compiles correctly on my i7 system (8 cores HT)
with encrypted APFS

The following hack allows gcc 7.2.0 to complete the 3 stage bootstrap of the
c,c++,fortran,lto,objc,obj-c++ language set under High Sierra on an APFS
volume...

I managed to reproduce this issue on an 8 core non-HT system booted from an
APFS volume on an old SATA2 HDD so the issue doesn't seem to be dependent on
really fast IO...

My VM has two cores, and repros this problem.
I reported this to Apple, who assigned the bug ID rdar://33924943. It was
reported to me that Apple engineers believed it was fixed in the latest beta,
but it is

Thanks. My system is a Core i7 (HT enabled), so I have 8 cores, good catch!
