Thank you for your quick and informative reply. I changed the loop to

     while (1) {
         pfNode* node = pfdLoadFile( "houston_named.3ds" );
         pfFrame();
         pfDelete( node );
     }

and now it creashes after one frame with

Unhandled exception at 0x103c808d in pfdbuildtest.exe: 0xC0000005:
Access violation reading location 0x07151ffc.

What needs to be added to the loop for it to not crash?

Why am I doing this? I am tracking a very obscure bug that manifests
itself exactly as an "Access violation reading location 0xXXXXXXXX." In
my real app I am keeping many builders and calling pfdBuild repeatedly
on them. An access violation happens after a varying amount of time.
Therefore I am trying to isolate the bug.

Thanks.
