Program:
---8X---------------------------
#include<fstream>
int main() {
std::ofstream file("test.txt");
std::streampos startpos = file.tellp();
file << 10;
std::streampos endpos = file.tellp();
assert(endpos != startpos);
return 0;
}
---X8---------------------------
compile at g++ 3.4.3 and work fine, but fail after compile at g++ 4.0.0
20041215 (mainline).
Also note: if set LD_LIBRARY_PATH point to gcc_34/lib (my gcc 3.4 lib
directory)
compiled with g++ 4.0 program work fine (using old gcc 3.4 shared libraries).
I think problem in code of "libstdc++.so.6" or "libgcc_s.so.1"
