Hello,
I'm in the process of converting some code that runs
under cc to gcc. I have discovered one thing that will
run fine in cc, but causes a segmentation violation for
gcc. That is, if I pass in a string constant to function which
declares the argument as a pointer to char, the program crashes
the moment I try to modify the contents of the string. Now,
it seems like this should be an error, but cc allows this, no
problem.
My question, is this discrepancy due just to the fact that cc
and gcc are implemented differently, and cc maintains its string
constants in different place that gcc? Or is it an ANSI requirement
that this situation be an error....
Jason
