I'm attaching make.exe.stackdump (another new feature of cygwin, cool).

Sadly, error_start didn't seem to be able to start gdb:

$ export CYGWIN=error_start:/usr/bin/gdb
$ make
*** starting debugger for pid 2156, tid 496
      4 [main] make 2488 try_to_debug: Failed to start debugger: Win32 
error 3
*** continuing pid 2156 from debugger call (0)
Signal 11

but hopefully the stackdump file will give you what you need.
