Package: html2ps
Version: 1.0b3-3
Severity: normal
Tags: upstream patch
Running html2ps on files with largish EPS images (using the --original
option) can cause the program to segfault. After some examination with
perl -d and gdb, it turned out that perl's regexp matching engine blows
the stack with thousands of frames. I don't know exactly what causes this, but
it probably has something to do with $&:s implementation.
The following trivial patch seems to fix the problem, and it also makes
EPS handling noticeably faster:
4320c4320
< $npr=$ps=~s|(.*\n){$nli}|sprintf("$&} D\n/P$nimg\_%d
{",$n++)|eg;
---
> $npr=$ps=~s|(.*\n{$nli})|sprintf("$1} D\n/P$nimg\_%d
> {",$n++)|eg;
Sorry for not providing more information, but since the bug occurs
mostly with large EPS files, I don't have a practical minimal example.
In any case, applying the patch can't do any harm.
