Log of an attempt to compile a universal binary for 10.5.6 for 2.3-dev (trunk)
keybounce:
I am the first to admit that I do not know what to look for. But, playing around with GDB, I found something that looks interesting.
It looks like the map data is being generated bad.

Leaf looks good, but brushnum looks bad. So part of trace_data looks good, and part of it scrambled.

There's enough obvious meaningful information in there that I don't suspect an invalid pointer, but some of the data in there is invalid -- it's crashing in the next subroutine down.

--- End code ---
Numleafs looks good, and this isn't the first time through the loop. So the data seems to be partially valid, and partially invalid.
As a side note: Do not use "i" as an array subscript. Reason: The notation "[ i ]" in code triggers bbcode ...
Mattn:
the brush num doesn't look bad - i mean 537 isn't really that high.
if you activate the developer mode (developer cvar to 1) you can see how many nodes, leafs brushes and so on are loaded on map start. please try to compare them with the numsides, numbrushes, numleafs and so on. i had a look too, and i can't find any missing endian swap for the bsp data. maybe there is some memory corruption. did you ever use valgrind (is it even available for macosx?). if you could run it in valgrind (execute ./contrib/scritps/valgrind.sh ufo from trunk/), please send the output (but be warned, it's damn slow in valgrind ;))
did you compile the wilderness map yourself?
keybounce:
Valgrind turned out to be real fast:
Kleiman-ibook:trunk michael$ ./contrib/scripts/valgrind.sh ufo
readlink: illegal option -- f
usage: readlink [-n] [file ...]
is no executable
Kleiman-ibook:trunk michael$
Kleiman-ibook:trunk michael$ valgrind
-bash: valgrind: command not found
Kleiman-ibook:trunk michael$ man valgrind
No manual entry for valgrind
I don't think it's there.
Yes, I compiled wilderness myself.
===
Now a question on "make maps" versus "./ufo2map". "Make maps" normally adds in "-extra", and we were told by another mac developer that it takes about 5 days. I have used ./ufo2map, without -extra; when I removed that from the makefile, it only took overnight.
I'm going to try a map with -extra, and see what that's like.
keybounce:
I think something got missed on a recent check-in:
This is from a make clean.

Alright, if you can tell me what to look for, I can provide you with any information you want. I've got a null pointer dereference right now.

All maps compiled locally.
"Wilderness" compiled with -extra
