In addition to those noted in pr65479 the following failures are seen in runs
of the the Address Sanitizer test suite (both C and C++):

The output of the tests suggests that the failures are due to incomplete
support for the support makecontext/swapcontext functions:
Child stack: 0x3fffd4ef9870
==41773==WARNING: ASan doesn't fully support makecontext/swapcontext functions
and may produce false positives in some cases!
