🚀 go-pugleaf

A doubly defined class that has both an explicit constructor and destructor
puts the compiler into an infinite loop. In the following example, I killed
cc1plus after 138 seconds:

------------------------------------------------------------------------
% cat bug.C
class loop
{
   loop();
   ~loop();
};
class loop
{
   loop();
   ~loop();
};
% time gcc -v bug.C

gcc has been installed without changes, but it has been compiled with "-O2" 
instead of the suggested "-g -O".
