New submission from STINNER Victor <vstin...@python.org>: test_compile and test_multiprocessing_forkserver crashed with segfault (SIGSEGV) on AMD64 Ubuntu 3.x: https://buildbot.python.org/all/#/builders/708/builds/31
It *seems* like test_compile.test_stack_overflow() crashed, but the log is not reliable so I cannot confirm. According to buildbot, the responsible change is: "bpo-43693: Un-revert commit f3fa63e. (#26609)(10 hours ago)" https://github.com/python/cpython/commit/3e1c7167d86a2a928cdcb659094aa10bb5550c4c So Eric, can you please investigate the change? If nobody is available to fix the buildbot, I suggest to revert the change.
