#include
#include <stdio.h> struct A { }; int main() { int *i = 0; try { i = new int(0); throw A(); } catch (const A &a) { printf("%d\n", *i); } } Compiled with optimizations enabled (-o+all), the compiler assumes that i is still NULL when the exception is caught: [...] xor ECX,ECX push dword ptr [ECX] push offset FLAT:_DATA call near ptr _printf [...] Extracted from omniORB (it only occurs when an omniORB application exits and omniORB tries to clean up...) bye, Christof -- http://cmeerw.org JID: cmeerw jabber.at mailto cmeerw at web.de ...and what have you contributed to the Net?
