I see.

As I told you in my previous message, this is the fallout of the fix for 
libstdc++/6518, which makes ostream::operator<<(const char*) more robust 
wrt null pointers but also sets the failbit in that case (OTOH, many 
other implementations of the standard lib do not set the failbit in such 
case).

For the time being, you may workaround the problem by always checking 
/explicitly/ that the const char* passed to ostream::operator<<(const 
char*) is not null, doing nothing in that case, i.e., not calling 
operator<< at all.
(f..i, for the lines "temp_file << ident_buffer << '\n';" and "temp_file 
<< buffer << '\n';")

Ciao, Paolo.
