* mem-break.c (check_mem_write): Add `myaddr' parameter. Don't
clobber the breakpoints' shadows with fast tracepoint jumps.
* mem-break.h (check_mem_write): Add `myaddr' parameter.
* target.c (write_inferior_memory): Also pass MYADDR down to
check_mem_write.
gdb/testsuite/
* gdb.trace/trace-break.c: New.
* gdb.trace/trace-break.exp: New.
