Building LuaD fails on Windows

[aubade]

I'm using the 0.13.0 release on windows, with the mingw build recommended in the README.txt file, and when I try to download and run the unit tests on LuaD using dub, the compiler seems to be crashing somewhere:

Running the commands:
dub fetch luad
dub test --compiler=ldc2 --arch=x86

It errors out with the following text:

Thanks for the report. I try to reproduce this now.

Ok, I can reproduce it. The error is in luad.table, line 299. ldc2 -c -unittest luad/table.d is enough to trigger the error. I now try to create a reduced test case.

Quick fix is to change line 4177 in dmd2/func.c from

if (semanticRun >= PASSsemantic3done)
{
    assert(cs);

to

if (semanticRun >= PASSsemantic3done && cs)
{

The DMD source assumes that the statement of a FuncLiteralDeclaration is a CompoundStatement. But in this case it is a TryFinallyStatement. Therefore the assertion fails, causing the error.

I still need to investigate if this is a genuine frontend bug or if the bug occurs because of a AST rewrite in LDC specific code.

Fixed in master.
