#1427 closed defect (fixed)

FT: Intro crash (regression)

Reported by: eriktorbjorn Owned by: sev-
Priority: normal Component: Engine: SCUMM
Keywords: Cc:
Game: Full Throttle


When I try to run the Full Throttle intro with today's
CVS snapshot, compiled under MinGW, it crashes after
the line "You know Ben, we're broke." with the
following backtrace:

Line 725 is simply free(chunk_buffer); so there's
probably some memory corruption going on. I haven't
looked into it any further than that, though.

Fortunately you don't have to sit through the first half of
the intro. Pressing Esc once should advance the intro to
shortly before the crash.

I believe codec is 37 right before the crash, but of course
the corruption could have happened before that. Perhaps
someone could valgrind the intro?

This has nothing to do with codec37. Just stack apparently
gets overwritten andbacktrace is wrong. This was caused my
changes to smush player so it can draw overlayed frames used
in FT INSANE sequences.

I restricted it to be insane-only, as .san files (smush
video) have smaller frames which serve unknown purpose at
the moment.

Bug is fixed.
