>Description:
Hunspell dumps core on amd64 when correcting a LaTeX file.
>How-To-Repeat:
Check a LaTeX file with hunspell on amd64 using the '-t' option.
>Fix:
Hunspell crashes because the calculation of PATTERN_LEN in
sr/parsers/latexparser.cxx does not account for padding.
I've supplied the fix to hunspell's sourceforge bugtracker. But in
case it gets lost, here is the patch.
