in/out contract overrides cause "cannot get frame pointer" error

WebDrake avatarWebDrake created an issue

This problem was observed with gdc 4.6.3 on Ubuntu 12.04.

Compilation fails when both an overridden class method and the one overriding it have in/out contracts. The compiler returns the following error for the attached minimal example:

inout.d:16: Error: function inout.B.foo cannot get frame pointer to require

Compilation succeeds only if the -release flag is used, which skips the assertions. DMD compiles the same code without problems.
