CURL_DOES_CONVERSIONS overwriting const data
Date: Wed, 27 Aug 2008 20:18:30 -0700
There are a number of places in the code where Curl_client_write() is
called with a string literal as an argument, e.g.
Curl_client_write(conn, CLIENTWRITE_BOTH, (char *)"Accept-ranges: bytes\r\n", 0)
Note the suspicious (char *) cast in there. If CURL_DOES_CONVERSIONS is
defined, then that string is passed to Curl_convert_from_network and is
converted IN PLACE to local host encoding (EBCDIC most likely). Problem is,
string literals are read only on many platforms and such a conversion will
cause a crash. Why doesn't this on TPF (presumably, the only platform to
use this right now)? Are strings there writable? This should be fixed to
generalize it to more platforms unless I'm missing something.
