breakpoint-hit event doesn't respect target.source-map for remote target

[brownts]

The "fullname" field in the breakpoint-hit stopped event doesn't contain the mapped path. I've captured both the lldb-mi and gdb commands and traces for comparison. Based on the mapping the /usr/src/hello_world.c source path should be mapped to /home/troy/git/hello_world_c/hello_world.c, but is instead being reported without the mapping (i.e., /usr/src/hello_world.c).

Additionally, bkptno doesn't match the actual breakpoint number either.

lldb-mi

commands

lldb-server gdbserver 0:2345 hello_world &
lldb-mi
settings append target.source-map /usr/src /home/troy/git/hello_world_c
settings show target.source-map
-target-select remote 0:2345
-break-insert -t -f main
-exec-continue

lldb-mi trace
