Make makes shell dump core....

Subject: Memory fault in shell using make...

	Subject: bug in 4.2 /bin/make

	SYSNOPSIS:
	    make sometimes dumps core with a memory fault or segmentation fault

Yes, I have seen the same behavior with our make, however
our shell blows up ONLY when make tries to do a make depend.

Needless to say, I'm somewhat concerned... especially if the
bug is in the kernel.

Using our brand new friend, Mr. DBX, I find that the command string
from the makefile is passed properly to the Bourne Shell, by make.
After the shell is vforked we suddenly intercept a trap and a maze of
4.2 signal routines are called (apparently due to some sort of
memory problem from within the shell) with a core dumped.

Make performs fine when I try to remake, say ''make'' or
any other particular piece of code.  When I try to remake the
kernel, however, the bourne shell goes bonkers.  But what
could be making the Bourne shell barf like this?

The makefiles in /usr/sys look okay, and I haven't made any
kernel changes yet.  Only reconfiguration of the system
hardware.  I don't think it has anything to do with swap space.

Now, I'm not exactly desparate or anything.... I took the cheap
and easy way out and reloaded the system code from tape (heh heh).
But I still find it disconcerting that such can happen.
Thanks in advance if you have any suggestions or fixes.
