digitalmars.D - D 2.066.1: Assertion failure: '0' on line 2022 in file 'mtype.c'

Hi,

after the update from 2.066 to 2.066.1
DMD gives following output:

Assertion failure: '0' on line 2022 in file 'mtype.c'
abnormal program termination

Unfortunatelly I do not know how to create a reproducible
example as the error occurs in a huge application.

DMD doesn't give me more information. I try to find out more
(reproducible example).

Kind regards
André

Based on the location of the error, I'd guess it's to do with passing a 
delegate to a templated function / as a template argument. (but it's 
possible it's not a delegate)

To find the error:
- Run dmd with '-v', it should tell you which function it was compiling when 
it crashed (the last one it lists).  Once you know the function it should be 
easier to determine which bit of code causes the crash.
- Or use dustmite to reduce the test case.

I will create a issue for this. The minimized version is:

enum DummyStringEnum
{
	foo = "bar"
}

class Test
{
	 property DummyStringEnum e()
	{
		return DummyStringEnum.foo;
	}
}
	
void main()
{
	import std.json;
	JSONValue[string] jsPayload;
	jsPayload["A"] = __traits(getMember, new Test(), "e");
}

Kind regards
André
