I've rebuilt 'make' with debugging info and started a GCC build. The
build failed as expected and I've got a core file to examine. Make dies
in the record_files() function in read.c at line 1918. The 'this' variable
is null, so 'this->name' fails.
$ gdb make core
...

Man once surrendering his reason, has no remaining guard against absurdities
the most monstrous, and like a ship without rudder, is the sport of every wind.
