Good, so there is no error in the code due to forced return 0 all is ok now :) Will read : http://www.hep.wisc.edu/~pinghc/isocppstd/basic.html Thx for the support, Laurent -----Message d'origine----- De : Andrew Haley [mailto:aph@xxxxxxxxxx] Envoyé : jeudi 22 mai 2008 14:09 À : Laurent Dufréchou Cc : 'Tom Browder'; 'Sven Eschenberg'; gcc-help@xxxxxxxxxxx Objet : Re: G++/GCC not detetcing stupid errors in code.

ISO/IEC 14882:1998(E) 3.5 Program and linkage "A return statement in main has the effect of leaving the main function (destroying any objects with automatic storage duration) and calling exit with the return value as the argument. If control reaches the end of main without encountering a return statement, the effect is that of executing return 0;" Note that this is a difference between C and C++: in C you must have a return value.
