Re: [fpc-devel] Type Compatibility: dynarray <=> Pointer

That compiles as well because Pointer(0) is converted by the compiler to nil. There is even a dedicated warning for this when used in a const: http://docwiki.embarcadero.com/RADStudio/Tokyo/en/W1013_Constant_0_converted_to_NIL_(Delphi) Am 17.04.2018 um 13:24 schrieb Martok: Am 17.04.2018 um

[fpc-devel] Type Compatibility: dynarray <=> Pointer

Hi all, I have started debugging 0031215, and discovered something slightly unrelated, but odd. I hope someone can clear that up. While testing, I found out that the following compiles, and becomes a call to fpc_dynarray_assign: var arr: array of byte; begin arr:= Pointer(42); end. This
