Yes, it dumps core before the creation of the file. I really don't know 
what's the problem here. Actually, grosscheck checks that arg is defined 
   at line 82 of the code:

	assert(arg);

But the code crashes at line 98

         strncpy(buffer, arg, *arglen);

Only thing I can think of is that arglen is wrong and strncpy writes 
beyond buffer. There should be check in the code for that, for debugging 
you could add a line:

	assert(*arglen < SBUFLEN);

Place it somewhere between assert(arg) and strncpy.

Hope this helps,
