Under gcc / gdb on Linux you can catch C++ exceptions in the debugger
with a breakpoint in __cxa_throw. Apparently, this is not so on FreeBSD.
I guess you need to google around for "FreeBSD exception gdb" or
whatever to find what is going on.

The kernel is irrelevant here :-) you prolly want debuginfo symbols for
libstdc++ glibc etc. (and/or whatever C++ runtime pieces you have).

So we can't find where the exception is thrown - which is a shame.

And this is not that helpful ;-) you need to do: "backtrace" when it
fails to get some clue what went wrong.
HTH,
