On the buildbot "SPARC Solaris 10 (cc, 64b) [SB] 3.x", Python crash randomly with bus error. It looks like a regression introduced since the build 1422. Since it's a crash, it probably comes from a change in C module and so I expected this changeset: http://hg.python.org/cpython/rev/2fbb3c77f1577acc60f57401e07d7feceea66841 "Issue #17919: Fixed integer overflow in the eventmask parameter." => see issue #17919 http://buildbot.python.org/all/builders/SPARC%20Solaris%2010%20%28cc%2C%2064b%29%20%5BSB%5D%203.x/builds/1422/ Change #34778 Category None Changed by R David Murray <rdmurray@bitdance.com> Changed at Sat 14 Dec 2013 16:26:20 Branch default Revision 561822250761b47d643656a0be9c71f9d770252b Comments #19970: fix additional typo in 3.4 asyncio docs.

Since tracemalloc is present many times in the dump and the error is an unaligned memory access, it looks the issue #20354 which I just fixed. (I also fixed issue #20162 which is another alignment issue, but it may be unrelated to this one.) |

Cool, the tests are no more crashing on this buildbot. I close the issue. |
