Bug 12585 – Regression(2.064): Segfault on lazy/catch/opIndex

This segfaults on 2.064 and newer (worked on 2.063.2): ----------------------------------- struct Bar { int opIndex(size_t index) { return 0; } } struct Foo { Bar opIndex(size_t index) { throw new Exception("Fail"); } } Foo foo() { return Foo(); } void catchStuff(E)(lazy E expression) { try expression(); catch(Exception e) {} } void main() { catchStuff(foo[0][0]); } ----------------------------------- On windows, adding dummy members to struct Foo leads to slightly different forms of crashing. Might be some sort of memory corruption.
