Re: I'm sorry...

As to why it worked on SunOS and IRIX, SunOS and Solaris have been known
for being very forgiving with memory access violations that should be
prevented while Linux is in general very unforgiving and appropriately
segfaults.  This is a case where as people have stated, you are
potentially illegally accessing read-only memory with a write and Linux is
behaving properly.  I would guess that IRIX would be just as forgiving as
SunOS/Solaris.  This is probably why SunOS and IRIX didn't puke like
Linux.  However, whenever you have constant literal strings you should
always think twice before altering them.  :)

Just my 2 pence.  :)
