I tried doing

strace -o logfile make test

but the output was too large, and the make seems to become slower and 
slower, after the file got to be over 2 GB and still growing, I killed 
everything.

So, I tried this next:

edited the Makefile and added  "-d" to the perl command in the Makefile, 
then typed

$ export PERLDB_OPTS="NonStop frame=2"
make test

This below is a small part of the screen output around the perl crash, 
may be this will help?

again, i am not familar with perl or debugging it, but will be happy to 
help, if you have some specific instructions I can try.
