@cxong Also, the editor crashes once I insert a level with:


Program terminated with signal SIGFPE, Arithmetic exception.
#0  ObjAdd (amo=...) at /home/clemens/Projekte/cdogs-sdl/src/cdogs/objs.c:392

Please try again; I've added a possible fix

@cxong Thanks! That fixed it, but now I get a crash after finishing the round of a dogfight. When you are at the intermediate score screen and then press enter, it crashes with this stacktrace:

Program terminated with signal SIGSEGV, Segmentation fault.
#0  strlen () at ../sysdeps/x86_64/strlen.S:106
106 ../sysdeps/x86_64/strlen.S: no such file or directory

According to some SO entry it may be that NULL gets passed to strlen, but since strlen is written in assembly, gdb can't make sense of it.

Can you give a full stack trace? I can't tell where in the code that is

ghost commented 8 years ago

@cxong Right, sorry, I completely forgot that is possible.

@cxong Confirmed, thanks for fixing.
