and it doesn't happen on kfreebsd-i386.

I'm getting the following backtrace on asdfasdf.debian.net:

(gdb) disassemble 0x0000000803cfa2c7
Dump of assembler code for function __pthread_sigsuspend:
   0x0000000803cfa2c0 <+0>:	mov    $0x155,%eax
   0x0000000803cfa2c5 <+5>:	syscall 
=> 0x0000000803cfa2c7 <+7>:	retq

i.e. the segfault is triggered from the kernel itself.

Does anybody has any idea?  I'd tend to reassign this to libgcj12 or
kfreebsd-8, since there doesn't seem to be anything specific to trang in
this backtrace.
