Got it. I'm attaching a minimal test case. glibc's makefile requires that Make be able to handle 140 levels of include recursion, but cygwin Make crashes after about 130 -- unless you're running under gdb or strace, in which case it works fine. To repeat the bug, just unpack the two attachments and run 'make'. If you have the bug, it will crash; otherwise it will echo a list of 140 words.

You should probably investigate using the CYGWIN environment variable "error_start" field:

Also, please send the output of the stackdump file here.
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. - Dan
