Subject Re: [drlvm][jira] Created: (HARMONY-2956) [jit] segfault with -Xem:server option
Date Wed, 10 Jan 2007 08:30:36 GMT
Naveen,

Using gcc 4.1.0 or newer will likely help in your case. There was JIRA issue
about similar failure:

http://issues.apache.org/jira/browse/HARMONY-1873

The comments reads that earlier gcc version have a bug in std::sort
implementation. That particular issue was fixed by simplifying the
comparator expression but the root cause is a bug in gcc.

Thanks,
Pavel
