Summary:	interpret.c:1421 assertion failure on CTFE code

Description Daniel Keep 2007年12月19日 20:51:26 UTC

When the attached source file is compiled with DMD 1.024 on Windows XP, the compiler generates the following output:
Assertion failure: 'v' on line 1421 in file 'interpret.c'
abnormal program termination
Sorry the test case is so large; it's very, very difficult to cut down CTFE examples when it's almost impossible to tell why something is or is not evaluable at compile-time (hint, hint! :P)

Comment 1 Daniel Keep 2007年12月19日 20:52:26 UTC

Created attachment 217 [details] 
Causes assertion failure
Compiled with the following:
dmd cr_test

Comment 2 Matti Niemenmaa 2007年12月20日 04:16:46 UTC

Brought it down to the following:
struct PR
{
}
int crRegister_ctfe()
{
	PR pr;
	pr = PR();
	return 0;
}
const i = crRegister_ctfe();
The problem appears to be assigning a struct literal to an already-declared variable. "PR pr = PR();" works fine.

Fixed dmd 1.025 and 2.009
