http://d.puremagic.com/issues/show_bug.cgi?id=5064 Reduced test case.

http://d.puremagic.com/issues/show_bug.cgi?id=5064 Further reduced. Shows it is caused by an closure passed as an alias parameter, + a struct with initialized members. If you remove the '=7', it won't crash. ---- struct Map5064(alias fun) { int xxx = 7; void crash() { fun(); } } void bug5064() { void delegate() dg = (){ }; Map5064!( dg ) q; q.crash(); } void main() { bug5064(); } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
