           Summary: optimizer assert on cdouble to bool conversion
           Product: D
           Version: unspecified
          Platform: Other
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD

this code:

cdouble c;

int main()
{
    if (c) return 0;
    return 1;
}

compiles with dmd 2.053 unless optimizations are turned on:

c:\tmp>c:\l\dmd-2.053\windows\bin\dmd -O ccmp.d
Internal error: ..\ztc\el.c 904

Considering the patch, I realized that

double c = 0.5;

void main()
{
    assert((c ? 0 : 1) == 0);
}

runs fine when compiled without -O, but asserts with -O.
