I tried updating to Brltty 5.2 from 5.1, but there seems to be a
problem with the interface to the latex-access executable table.
Specifically, Brltty works fine until I try and switch to contracted
braille using latex-access at which point the Brltty process
immediately dies.
I found a problem within the code that caused a crash for me. It's now fixed in
the latest development code. Could you please give it a try.
Unfortunately that hasn't fixed it. I managed to get a core file loaded
into GDB so I can give you some more information. Execution eventually
ends up in getContractionTableCharacter which tries to call
getContractionTableHeader which fails because its an external table.
Some of the traceback is below, do you have any ideas?
