Thanks for the info, but I removed the custom build and got those problems.

Thanks for the hints, but everything is "default" here: one internal sound card
which eSpeak correctly addresses with brltty-espeak 4.5.

Finally it was a incorrect configuration directive which prevented eSpeak from speaking (which worked with 4.5 though):
speech-parameters es:PunctList=.,\!"§$%&/()=?{}[]

The crashes mentioned above are actually hangs of the display, I can now
reproduce with speech enabled: while speech is fine, braille stops after a half
minute or so; it can be brought back by pressing a key on the display. I'll test
whether this is an upstream regression.
