Bug 639 – Escaped tuple parameter ICEs dmd

// credit goes to http://pc8.2ch.net/test/read.cgi/tech/1158013550/956 T* f(T...)(T x) { return null; } void main() { auto x = f(2,3,4); *x = *x; } ---------------- Assertion failure: '0' on line 697 in file 'glue.c' abnormal program termination Although dmd 0.176 prohibits tuple return types, it still seems to suffer pointers-to-tuple, arrays-of-tuple, etc.

Some test cases that didn't cause DMD-1.010 to ICE cause DMD-1.013 to ICE: http://dstress.kuehne.cn/nocompile/t/tuple_06_B.d (-O, -inline, -release and combinations thereof) http://dstress.kuehne.cn/nocompile/t/tuple_06_F.d (-g)

Fixed DMD 1.018 and DMD 2.002
