You can enable debugging, but this probably isn't enough. I would suggest also
enabling the generation of core files from the shell in which you run brltty:

ulimit -c unlimited

If it crashes, it should create a file with "core" in the name, which you can
then load into gdb and obtain a backtrace.

You might need to build BRLTTY with debug symbols, however, for this to work.
Note that the -l 7 option will increase the logging level to debug.
