[GEM-dev] Model loader under OSX

[ben at ekran.org]

Hey all,

I'm trying to load an obj model into Gem OSX and it just seems to crash.
The packaged venus.obj file works fine. Here is the PD output:

_glmFindMaterial():  can't find material "vn".
_glmFindMaterial():  can't find material "vn".
_glmFindMaterial():  can't find material "vn".
_glmFindMaterial():  can't find material "vn".
_glmFindMaterial():  can't find material "vn".
_glmFindMaterial():  can't find material "vn".
_glmFindMaterial():  can't find material "vn".
_glmFindMaterial():  can't find material "vn".
_glmFindMaterial():  can't find material "vn".
_glmFindMaterial():  can't find material "vn".
_glmFindMaterial():  can't find material "vn".
_glmFindMaterial():  can't find material "vn".
_glmFindMaterial():  can't find material "vn".
*** malloc[500]: error for object 0x20c6690: Incorrect checksum for freed
object - object was probably modified after being freed; break at

gdb tells me:

I've attached the offending obj file (I tried three that all don't work)

Sorry about the anoying "watchdog" messages interdispersed... but thats
another email to pd-dev.

Thanks
Ben
