I think I can reliably reproduce this. After checkout, if you run ./bootstrap.sh, it should cause "flisp.boot" become an empty file. if you then run make, it would cause the crash during test.

I concur,
git clone https://github.com/JeffBezanson/femtolisp
cd femtolisp && ./bootstrap.sh
make
=> segfault
but
git clone https://github.com/JeffBezanson/femtolisp
cd femtolisp
make
=> success
