Category: 68. Win Window Operations Group: development: 8.6b3 Status: Open Resolution: None Priority: 8 Private: No Submitted By: Don Porter (dgp) Assigned to: Chengye Mao (chengyemao) Summary: winWm-9.2 segfault Initial Comment: In an --enable-aqua build of Tk8.6b3, running the test suite on Snow Leopard segfaults on test winWm-9.2 . If I use -match to run only that test, there is no segfault. It may be that this test isn't appropriate to run on Mac OSX, I don't know, but even so a segfault triggered by script eval is a bug needing a fix. ---------------------------------------------------------------------- >Comment By: Don Porter (dgp) Date: 2012-09-14 14:26 Message: See branch bug-3567779 for attempt at a fix. ---------------------------------------------------------------------- Comment By: Don Porter (dgp) Date: 2012-09-14 12:05 Message: WIth --enable-symbols=mem, it's clear that the winPtr passed into TkWmDeadWindow is pointing to ckfree'd memory. ---------------------------------------------------------------------- Comment By: Don Porter (dgp) Date: 2012-09-14 11:45 Message: Segault is in the routine TkWmDeadWindow() The value of wmPtr is not a valid pointer, nor is it NULL, so when wmPtr->hints.flags is attempted, we crash. Might be logic; might be memory corruption. ---------------------------------------------------------------------- Comment By: Don Porter (dgp) Date: 2012-09-14 11:34 Message: Segfault is in the command wm forget .t.f ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=112997&aid=3567779&group_id=12997 |
