compile problem

[Len Jacobs]

After 2 years of relatively error free performance on a 3B1 running 3.51
I have begun to have a strange problem:  cc compiling produces
non-execuatable binaries.  So the following phenomenon:

[1] cc foo.c
[2] a.out  
Memory fault - core dumped
[3] 

This happens regardless of the simplicity of foo.c.  Does this
provide enough clues to determine what could be the cause?

I would appreciate any help or comments.

Thanks.
