Hybrid Skeletal animation ala tutorial 15 - bug?

Post  Tom on Thu May 28, 2009 6:56 am

I have a very simple model that I am using to animate a 2d-ish character in orthographic projection mode, using the skeletal animation technique demonstrated in tutorial 15.

I had my character animating the legs and walking fine and it looked great. Then I added bones for the arms and my application still works, now whenever I try to add a keyframe for one of my arm bones my app will crash at load time at the line:

141: _SIO2frame->buf = ( unsigned char * )malloc( _size );

in sio2_frame.cc, and displays:

tutorial15(1604,0xa00e2720) malloc: *** error for object 0x187ac00: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
tutorial15(1604,0xa00e2720) malloc: *** error for object 0x187ac00: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug

in the log.

I don't even think it is an sio2 error because I tried changing the line to:

unsigned char *testBuf = ( unsigned char * ) malloc ( _size ); and that failed too..

and unsigned char *testBuf = ( unsigned char * ) malloc ( 996 );
fails too.. 996 is the value of _size;

howerever malloc (1) works.

I seriously doubt I am out of memory however??? Have I just found a compiler bug with the 3.0 sdk? Anyone have any ideas of what I could try?

Use malloc debug there's obviously a leak somewhere and since the frame is shaking alot of memories you are seeing the symptoms here...

Yeah the problem was with my art assets. Shared faces among vertex groups causes all kinds of madness. Got to be really careful about what faces are in what groups and what not it seems.
