Prevent parzu crashes about parzu

[rsennrich]

Hi Eleftherios,

this is a bug in swi-prolog 5.8 or so (I assume you use Ubuntu 12.04).
Downloading and using a recent version of swipl should fix the bug.

I'm assuming the ID is correct because ParZu is doing some parallel
processing and one thread might be processing sentence 299 before the
others have been parsed.

best wishes,
Rico

I am trying to parse our training data, and unfortunately every now

[Thread 1] pl-fli.c:2428: codeToAtom: Assertion failed: chrcode >= 0
Parser process 7070 has crashed on sentence 299. If you don't see
swipl error message, try parsing sentence in single-processed mode

First of all, the parser is probably reporting a wrong sentence id,
because the output file only has less sentences than 299. Using
--process 1 does not prevent the error from occuring.

I am not really interested for the particular sentence causing the
error, but I would appreciate it if the parser can go on with the next
sentence of the given file, instead of crashing.

to be more exact, I think swipl 5.8 is unaffected, 5.10 is buggy, and the bug is fixed in 6.2 or higher. I'm not sure where it was introduced/fixed, but these are the versions I tested.

I'm closing this issue; feel free to re-open if you encounter the bug with a recent swipl version.
