Summary: invalid use of setlocale

Initial Comment:
char *oldloc=setlocale(LC_CTYPE,NULL);

setlocale(LC_CTYPE, "C");

setlocale(LC_CTYPE, oldloc);



can cause strange problems.



The glibc documentation clearly states, that you must

make your own copy of the string.



>From glibc docs:

setlocale()



RETURN VALUE

       ... This  string  may  be allocated  in static

storage. ...



It means, that subsequent call of setlocale can

overwrite this string. And since glibc-2.3 it does.



There is a fix.
