SIGSEGV in GC in JVM 64-Bit Server VM (1.6.0_03-p4-root_05_feb_2011_09_13-b00 mixed mode)

[Charlie Martin]

We're running into this issue, which appears to be related to several 
bugs in the Sun bug database.

Does this appear to be a known bug?  Also, is there a bugtracker against 
the FreeBSD port?  I haven't been able to find it.

We're just beginning to track this down, but gdb dump shows us
