If it's not possible to reproduce the crash outside of your environment
then better would be for you to build GNU make with debugging enabled:

  make CFLAGS=-g

then run it so it crashes, then investigate the generated core file
with a debugger (gdb) and generate a stack trace to see where things
are crashing.
