PBRT consumes 100% memory and crashes using fourier material on teapot #79

The following pbrt file will reproduce the crash:

You'll also need the ceramic.bsdf and room-teapot.pbrt which can both be found in pbrt-v3-samples.

room-teapot.pbrt looks like this:

for 2000 lines so I'm guessing it tries to allocate a fourier BSDF for each triangle which causes it to eat up memory.

Fixed! Thanks!
