Originally reported in the bug tracker on 14th October:
    https://issues.dlang.org/show_bug.cgi?id=24814

Now tracked in an issue following migration:
    https://github.com/dlang/dmd/issues/20534

It relates to the fact that for x86-64 use of DMD, the 
va_copy/va_end facilities need to use alloca(), and the latter 
fails under betterC.  The latter also has its own bug:

    https://issues.dlang.org/show_bug.cgi?id=24815
    https://github.com/dlang/dmd/issues/18276

I had included a partial fix for the first issue, and the patch 
is also attached to the github issue.  More details are in the 
original bug ticket, and the thread it links to.
