Bug ID: 236
Summary: Empty structs not copied correctly
Product: GDC
Version: development
Hardware: ARM
OS: All
Status: NEW
Severity: minor
Priority: Normal
Component: gdc
Assignee: [email protected]
Reporter: [email protected]
There's a failing unittest on ARM in rt.aaA. The test uses a struct without any
non-fields as an index for the AA. The hashing function for an empty struct
always hashes exactly one byte. It seems this data is not always copied when
assigning an empty struct. It probably requires the values to be passed on the
stack.
void foo()
{
int a;
}
struct NoField
{
//ubyte f;
}
void main()
{
foo();
NoField[2] fields = void;
fields[0] = NoField();
import core.stdc.stdio;
printf("%d\n", *(cast(ubyte*)&fields[0]));
}
