Asserting testcase
The following code is reduced from an example for boost::date_time. It compiles
fine with 'clang++ t.cc -c', but fails with 'clang++ t.cc -O' (or higher
optimisation level).
I believe this a boundary case somewhere, as the constant 9223372036854775807 (
= 2^63 - 1) appears, and changing this by one value up or down makes the code
compiler correctly. Apologies for the size of the testcase.
I strongly believe this test has worked at some point in the past, but I am not
sure exactly when.
