I finally started to mess around with D and managed to crash the latest dmd
with this test program:
struct bittest_T(int C)
{
bit b[C];
};
void main()
{
for (int t=0; t<32; t++)
printf("sizeof bittest_T(%i) %i\n", t, bittest_T!(t).sizeof );
}
DMD prints this compile error (which makes sense):
C:\UTIL\d\fart.d(33): template instance fart.bittest_T!(t) cannot use local
't'
as template parameter
..and crashes with an access violation exception.
I ran DMD.EXE from MSDEV and it breaks at 0040B6D1:
0040B6CA 90 nop
0040B6CB 90 nop
(function entry point?)
0040B6CC 53 push ebx
0040B6CD 31 C0 xor eax,eax
0040B6CF 89 CB mov ebx,ecx
0040B6D1 88 00 mov byte ptr [eax],al
Pretty obvious: EAX is set to 0, and then used in a look-up?

Same crash with this program:
void main()
{
for (int t=0; t<33; t++)
printf("sizeof bittest_T(0) %i\n", (bit[t]).sizeof );
}
(Guess what I'm trying to do :-S )

D should complain with:
Integer constant expression expected instead of t
and does for me.

I just tested again, it really crashes. DMD 0.107 doesn't say a thing; crashes immediately. Doesn't print the link-line either so I guess it's the compiler. Running WindowsXP with SP2: Microsoft Windows XP [Version 5.1.2600] Digital Mars D Compiler v0.107 OPTLINK (R) for Win32 Release 7.50B1 L. (I've even tried running dmd from cmd.exe, 4nt.exe 5.00u and msdev6: no difference)
