DESCRIPTION OF PROBLEM:
|
|
=======================
|
|
|
|
The example map, maps/segmentation_fault.map, contains an example of this
|
|
bug. q3map2 might segfault while compiling this map. This sort of thing
|
|
might happen in certain intermediate versions of q3map2 while work is being
|
|
done on fixing the math accuracy. The bug may not have happened in older
|
|
version of q3map2, before the math accuracy issues were addressed.
|
|
|
|
To trigger the bug, compile the map; you don't need -vis or -light. Only
|
|
-bsp (the first q3map2 stage) is necessary to trigger the bug. The only
|
|
entities in the map are a light and a info_player_deathmatch, so the map will
|
|
compile for any Q3 mod.
|
|
|
|
Here is a description of the problem brush (brush #0):
|
|
|
|
side 0: -z face
|
|
side 1: +z face
|
|
side 2: -y face
|
|
side 3: +x face
|
|
side 4: +y face
|
|
side 5: -x face
|
|
side 6: problem side "accidentally showed up" :-)
|
|
|
|
Side 6 is actually a superfluous plane and will be NULL'ed out in the code.
|
|
If the code does not handle a NULL'ed out winding correctly, it will
|
|
segfault.
