Is the SIGBUS sent to the program being debugged, or to gdb itself?
Does the problem still happen when you don't set the breakpoints?  Can
you get a backtrace after the signal is caught?

The only time I've seen a SIGBUS on Solaris was when porting a Linux
application.  This was due to miscasting a pointer which caused a
memory alignment problem.  I didn't see the problem on Linux, even
though it was a genuine bug.  I've also seen subtle bugs that only
shown up in the debugger, but these have thankfully been a rarity.
