Bug 12487 – DMD correctly reports excessive CTFE recursion, but not template recursion

Created attachment 1340 Test case for crashing the compiler Compiling the attached test case reports: recursion.d(6): Error: function recursion.recFunction CTFE recursion limit exceeded recursion.d(7): called from here: recFunction(i) recursion.d(6): 1000 recursive calls to function recFunction recursion.d(14): called from here: recFunction(0) if dmd is run with -version=RecFunction, which makes very easy to spot the bug, but just prints Killed after running out of memory if run with -version=RecTemplate.

Duplicate of issue 12485?

In 2.067 and git-head, -version=RecTemplate compilation reports: test.d(3): Error: circular initialization of recTemplate test.d(11): Error: template instance test.recTemplate!int error instantiating Therefore the segfault issue is already fixed. However I think the diagnostic "circular initialization of recTemplate" is still unhelpful a little.
