Segfault with operator delete[]

[Brian Hart <bhart at nabhas dot ps dot uci dot edu>]

Hello:

I am using GCC v2.96 on Red Hat 7.3.

My C++ program ALWAYS seg faults when operator delete[] is called on a 
pointer, even though stepping through the code in the debugger reveals not
only the address to be valid, but also it is the same address as that 
returned by operator new.

This only happens when calling delete[] on arrays of primitive types 
besides char.  An example of offending code is:

unsigned long* v = new unsigned long[100];

/* the above succeeds, let's say */
/*snip*/
...
/*snap*/

delete[] v;  /*<-- seg fault here; why?? */
v = NULL;

Does this have anything to do with the compiler?  Oddly enough, if I 
use malloc()/free(), malloc() seems to work fine, but free() blows 
up.  Even if they are both given the same pointers.  ?? 

Thanks for any 
help.
