Greetings, I was trying to build www/firefox on netbsd-current (64-bit 
kernel and userland), but it kept terminating with "Bus error" and 
dumping core. So before submitting a PR I decided to build it with 
debugging symbols and look a bit deeper into it. The problem is when I 
run gdb on the core dump, it stops with:

/opt/src/gnu/dist/gdb/gdb/utils.c:981: gdb-internal-error: virtual 
memory exhausted: can't allocate 11640336 bytes.

An internal GDB error was detected.  This may make further
debugging unreliable.  Quit this debugging session? (y or n)

I'm not sure if this is sparc64 specific or gdb needs to be told to use 
more memory. What do you think?
