Trying more games the crash maybe OGG-related e.g., renpy (tutorial) and manaplus crash but gigalomania doesn't. (In reply to Jan Beich from comment #0) > $ pkg install abbayedesmor Typo: games/abbayedesmorts. Is this still a problem? Latest version doesn't seem to crash. I can't reproduce after ports r450461. Probably was a SDL bug. |
