Bug 15524 – [REG2.069] 64bit app with anon-class crashes in contract

This reduced code works in 2.068.2, but the program crashes in 2.069 and 2.070beta1. I tested with Win7 64bit. rdmd -m64 test.d --------------------------------- void main(string[] args) { auto t = new Test(); t.add("first"); t.add("second"); } class Test { int[string] infos; void add(string key) in { assert(key !in infos); // @@@ crash here at second } body { auto item = new class { void notCalled() { infos[key] = 0; // affects? } }; //dummy ~= item; // does not affect infos[key] = 0; } } Object[] dummy; ---------------------------------

In Win64, some function parameters are passed by registers (`SCshadowreg`). When the parameters are placed in closure context, their access was not well handled in #4788. Also in Posix 64bit platforms, parameter variables have SCauto. So there was same issue. https://github.com/D-Programming-Language/dmd/commit/ea553ad9ed1053db4348bda584df5380bf6d0eea Merge pull request #5420 from 9rnsr/fix15524 [REG2.069] Issue 15524 - 64bit app with anon-class crashes in contract
