tmpnam() core dumping

[Bill Ahlbrandt]

Yes, using -fwritable-strings fixes the problem.

I wonder why these functions want to modify the string that is passed to them :-)?

Thanks much...

Does -fwritable-strings fix the problem.

>From the GCC manual:
@itemize @bullet
@cindex string constants
@cindex read-only strings
@cindex shared strings
@item
GNU CC normally makes string constants read-only.  If several
identical-looking string constants are used, GNU CC stores only one
copy of the string.

@cindex @code{mktemp}, and constant strings
One consequence is that you cannot call @code{mktemp} with a string
constant argument.  The function @code{mktemp} always alters the
string its argument points to.


This may also apply to tempnam.
