Re: [freesci-develop] FreeSCI 0.6.4 rc3

Robert,

  first of all, thank you very much for your numerous and detailed bug
reports :-)

  I cannot reproduce any of those, and your core dumps don't seem to
contain sufficient information to track the issues.  It's quite
possible that all the crashes are the same issue, though, so a single
core with debug information might provide all the data we need.

  Can you re-compile FreeSCI with debug flags enabled, please?  For
this, please run

CFLAGS='-g -O0' ./configure && make clean && make

  The resulting binary may be noticeably slower and thus less suitable
for playing games in general, but, as I mentioned, a single core dump
from this binary might reveal all that is needed to identify the bug.

  Tracing the pointers for a bit, it seems to me that this is the same
architectural issue that also prevents you from importing savegames.
We will have to change the way we handle strings in order to fix this
problem (that's one of the most urgent to-do items).

  Very odd, particularly since it worked the first time around.  Until
we can reliably reproduce this somehow, I am afraid that there is
nothing I can do, though.

  I will get back to you on the other issues later today.
