This is something of a "Corona688-told-me-so" post.

I found the error, and it was a SEGFAULT-causing error. But it wasn't anything to do with Pari's novel memory management; just a simple mistake anyone could have made (and I was apparently boneheaded enough to make).

Code:
char* kept = getBValue(line);
GEN value = strtoi(kept);
if (kept == NULL)
	continue;

My function getBValue, if it cannot find a value in the line it is passed, returns NULL. Rather than testing its return value (kept) for NULL, I pass it to anther function... and only then test for NULL.

Smilie

How did I miss that?
