Confusing error for incorrect struct initialization

[lh mouse]

Those are GCC implementation details.

In spite that in most cases implicit conversion from an integer (except a null pointer constant, of course) to a pointer should be considered a casual error, it is however required by the C standard:
---
ISO/IEC WG14 N1570 Programming languages — C

6.3 Conversions
1 Several operators convert operand values from one type to another automatically. This
subclause specifies the result required from such an _implicit conversion_,  ...
...

6.3.2.3 Pointers
5 An integer may be converted to any pointer type. Except as previously specified, the
result is implementation-defined, might not be correctly aligned, might not point to an
entity of the referenced type, and might be a trap representation.67)
---

Making it an error would make GCC not conform to the standard just because C is so broken.

主题：Confusing error for incorrect struct initialization

Hello,

I opened bug 71552:

Confusing error for incorrect struct initialization
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71552

I don't understand Martin's reply in comment #1.

Could someone explain?

Regards.
