Subject [jira] Commented: (HARMONY-3666) [drlvm] crash handler sometimes deadlocks
Date Wed, 18 Apr 2007 03:03:15 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-3666?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12489592

Alexey Varlamov commented on HARMONY-3666:

Yep, that's why I used conjunctive mood...
One thing which bothers me is why the deadlock is intermittent? I suspect that segfaults in
AWT happen mostly due to double free, neverthless VM is sometimes able to handle signal properly
- I even got normal output once in a while, see linked HARMONY-3664.

> Running AWT tests with release VM, ~ each 3rd run hangs during stack dump. Usually this
happens if SIGSEGV happens early enough (up to 6-8 tests run), probably interfered with compilation.
I did not seen hangs on debug build, probably because of different timings.
> Anyway, almost always VM just prints "SIGSEGV in VM code." and either hangs or aborts.
