Comment 2 Anton Shterenlikht 2011-09-25 20:24:24 UTC 
Gerald has provided a fix for the _Unwind_FindTableEntry
FreeBSD ia64 issue
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45650).

With this fix, 4.7 on ia64 FreeBSD now gives the
same error:

Comment 4 Gerald Pfeifer 2011-09-25 20:45:38 UTC 
Well, my "fix" may not really be one (it definitely is a hack and not the
right fix) and thus it may actually be causing the segmentation fault even.

I think http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45650 may need to be
addressed for real first, before delving into this one.
Comment 5 Jakub Jelinek 2011-10-26 17:13:59 UTC 
GCC 4.6.2 is being released.
Comment 6 Jakub Jelinek 2012-03-01 14:39:18 UTC

Comment 7 Jakub Jelinek 2013-04-12 16:18:00 UTC 
The 4.6 branch has been closed, fixed in GCC 4.7.0.
