Reveals while porting old C library, below code crashes dmd v2.062 without any
error reported:

long gi;
enum gi0 = ((cast(int *)&gi)[0]);
enum gi1 = ((cast(int *)&gi)[1]);

void main()
{

}

If you port C code them maybe you want to write:


__gshared long gi;

(In reply to comment #2)
 If you port C code them maybe you want to write:
 
 
 __gshared long gi;

It is doesn't matter, this code doesn't have sence in D, enums are calculated in compile time, but preprocessor just pastes code in C. When porting C code, it is very difficult to find such error due dmd just crashes without any message. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
