 No it doesn't, not since 3.0 which is conforming to the standard
 and where str() returns a std::string.  Use std::stringstream,
 not std::strstream.

 hi!
 
 hmm, this is very strange, as it is NOT gcc's fault, but mine.
 
 *buf += str.str(); <--  this freazes the buffer and returns a
                         pointer to it. the caller is now
                         responsible for freeing it with delete().
 
 so, the testprogramm MUST memleak as it is, independently from
 the compiler. can you have a look at it, to make this clear?
 
 thanx & sorry for bothering you!
