Could a gatekeeper please review this patch? https://bugs.open64.net/show_bug.cgi?id=751 This assertion happens when StInfo::alignOffset doesn't return a pointer_size aligned offset constraint graph node.
The bug is quite direct in StInfo::alignOffset // If the offset is already aligned to Pointer_Size, there // is not need to adjust. It is the sub-pointer size offsets // that will cause issues, especially if the offsets to not // match up with a valid field offset in the current TY if (offset & (~(Pointer_Size-1)) == offset) however == has higher priority than & This problem is exposed when getting align offset constraint graph nodes for complex array. In setting modulus for complex, its treated as a structure with two elements. However in StInfo::alignOffset, it always aligns offset to the real part of the complex. Which cauese real part always alias with img part. Fix in StInfo::alignOffset 1. Correct computation order using parenthesis. 2. for complex, offset can be aligned to both real and img part.
