cfbolz changed the topic of #pypy to: #pypy PyPy, the flexible snake https://pypy.org | IRC logs: https://quodlibet.duckdns.org/irc/pypy/latest.log.html#irc-end and https://libera.irclog.whitequark.org/pypy | the pypy angle is to shrug and copy the implementation of CPython as closely as possible, and staying out of design decisions

<mattip> something strange is happening on windows. The own tests on py3.9 failed in build_executable_cache, claiming that WRYTE_OWNER from rwin32.py is not a valid identifier
<mattip> but in the file it appears as WRITE_OWNER, not WRYTE_OWNER
<mattip> on the buildbot's hard disk it is also correct, so it is somewhere after reading the file
<mattip> the rwin32.pyc file is also correct
<mattip> translation also segfaulted with an exit code -1073741819, which seems to be a STATUS_ACCESS_VIOLATION
<mattip> event viewer says that at the same time, there was an error in svchost.exe_defragsvc, also STATUS_ACCESS_VIOLATION

<mattip> maybe defrag was running somehow during the tests/translation?

<cfbolz> mattip: it's 1 bit difference, it clearly must have been cosmic rays
<mattip> maybe I can move the buildbot into a lead-lined saferoom

<arigato> yay, we can add "very likely a cosmic ray" in the long list of bugs that pypy found in other places than pypy
<mgorny> arigato: fwics you were correct, and ctypes in pypy is completely borked when libffi is built with assertions :-(
<mgorny> i've added a trivial reproducer and test results to the bug
<sam_> thanks mgorny
<mattip> asking the obvious: does the problem reproduce in cpython?

<sam_> no
