Today I just get a core dump with 32-bit x86:

Core was generated by `/home/bfriesen/build/tiff-head-32bit/test/.libs/raw_decode'.
Program terminated with signal 11, Segmentation fault.

I did add a change so that the test can be run with builddir != srcdir 
but this core dump seems unlikely to be due to those changes.
