Could someone please verify this bug in BCC32.EXE 6.16.0.33 (CodeGear™ RAD Studio 2009 Version 12.0.3170.16989):
typedef struct{ __int64 i; } S; void foo(){ S s={0I64}, *p=&s; p->i <<= 2; //AV /*workaround: p->i = p->i<<2; or p->i = Int64ShllMod32(p->i, 2); */ }

Where is your declaration of p?

@SergeyAKryukov Right at the end of this: S s={0I64}, *p=&s; Thus giving a pretty good reason why you shouldn't write dense code like this. Some people trying to help can't read your code well enough to help.

Recommendation: Edit the question to describe what happens instead of what should happen. Comparison of generated assembly and expected assembly is highly recommended.

Do you see the same problem with p->i *= 4;? Bit easier on the brain, maybe easier on the compiler.

What is "//AV"?
