Hi,
After re-loading a scene, we get a std::bad_alloc (with 3 gigs) from the
following place (line 601 in OSGShaderProgram.cpp):
if(iStatus == 0)
{
Char8 *szDebug;
GLint iDebugLength;
osgGlGetShaderiv( uiShader,
GL_INFO_LOG_LENGTH,
&iDebugLength);
szDebug = new Char8[iDebugLength];
^^^^^^^^
Looking at the values in a debugger, iDebugLength is stupidly large
(1768036544) so I think the glgetshaderiv fails and never writes to this
value. (Is it guaranteed to do that always?)
Anyway, the allocation fails, so we can't really figure out what goes
wrong. (We just load the same scene again..)
The call stack is included below.
I suppose I could patch OpenSG to set both szDebug and iDebugLength to
zero, and see if it helps. (It's probably a good idea anyway. ;)
I'll look into that after the weekend. Ideas in the meantime are welcome. :)
Cheers
