> Acknowledge that gcc builds work on the AIX buildbots (a fact that has been > entirely ignored so far). I do acknowledge that. I am not saying that I am sure there is a bug in the code. For what I know at this point it may be something with xlc, with the OS itself, with the libc version or something misconfigured on the machine. The only thing I know is that before I could run the test suite without any problem on 3.7.6 and now I cannot in 3.7.7, and because 3.7 a maintenance branch I though this is a possible regression, so I reported it. > are you using xlc or xlc_r? I am using xlc_r. I am saying xlc because that is the name of the compiler. The _r suffix activates thread-safe compilation (which I am doing). Apologies for the confusion. > State the exact regression The **exact** regression is that I could run the test suite without any crash or freeze on this AIX system with 3.7.6 and I cannot in 3.7.7. At the very least this is due to the fact that there is a new test that crashes/hangs. Why this happens I still have no idea as I am currently investigating. Debugging on AIX is not a pleasant task. > n short, given the flakiness of the xlc toolchain I'm not even sure if anything can be classified as a regression. Most xlc users I've talked to have switched to gcc. I notified the behaviour different here so we can discuss about this as a team. If we decide that this is xlc's fault or is not worth to investigate or that because AIX is not really fully supported we do not want to spend resources I can totally understand it. I thought this was important enough because this change was in 3.7, which is supposed to be stable across minor releases (the same applies for 3.8 if the problem also appears there). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39576> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
