Hello! I want to report a possible gcc bug. I hope it is really a bug and not my mistake. System : Athlon 1333, 512 MB RAM, Linux 2.4.18 (Debian Woody) Compiler: GCC 3.2.1 (compiled with 2.95.4 and options "-O2") Program : C++ using <vector> The concerning sources are attached. It is a program with 7000 lines but no complicated stuff. Only one function and some vectors. Without flags it compiles within eight seconds. But if I use "-O" the compiler (cc1plus) needs slowly more and more memory and has possibly entered an invinite loop. After 30 minutes it needs 193 MB RAM and is still working. I tried it several times for up to 30 minutes before canceling the compiler. GCC 2.95.4 works and needs with "-O" rather long 70 seconds to compile the program. The problem seems to be in my function init(). Because a plain init(){} works. But I couldn't find details, because this small program works: --------------------------------------- include <cstdlib> include <vector> using namespace std; int main () { vector<vector <vector<int> > >v; v.resize(10); v[0].resize(10); v[0][0].resize(100); v[0][0][0]=5; return EXIT_SUCCESS; } --------------------------------------- And init() contains only such commands. So I attached the big function init() as it is and gziped it. GCC 3.0.4 seems also not to work. I hope this description helps you. Thanks, Stephan Trebs
