No it's not. Members are always at a fixed location within classes. Under what situation do you imagine it returning random garbage?

It looks like old code written to be portable before "offsetof" was widely available. It's not dereferencing a NULL pointer, it's getting the address of a member variable when the "this" pointer is NULL which is equivalent to finding the offset of that member (in bytes) from "this".

That's exactly the same name shown in your screenshot, how is it incorrect?

It can send midi (MPU-401) to a midi output... adlib is completely different.

There's quite a few games with broken audio at the moment, it's still a work in progress.

New patch attached. This uses the same strategy for both windows and other platforms (separate mappings for writing vs. execution). It merges cache.h from both dynamic cores since they were already 95% identical. I had to touch a fair bit of code for platforms that I can't actually test (mips and …

Yes, the "boot" command only supports drives mounted as images.

Probably best to run the check only for darwin targets, like the "whether Apple user wants to override the build process to produce a 32 bit binary" test for example. Not a showstopper but will speed up configure a little bit.

Knowing Apple, I expect their gcc builds to choke on their more recent framework headers.

Do any copying before running the boot command.

That's normal. You can't mount drives after using the boot command, and any drives that aren't images are unavailable.

I'm not sure, however Apple's modified gcc needs to support the Blocks extension otherwise #include'ing Apple's coreMIDI header would similarly choke on the broken prototype syntax. The versions of xcode that bundle gcc don't bundle system headers that use blocks, obviously. The preprocessor code …

This is a bog-standard gcc... and it builds DOSBox just fine when I use Apple's own published method for dectecting their AppleBlocks extension. It's not fine though, it's crippled - missing a standard feature that a macOS build is expected to have. Have you checked if Apple's gcc ( not clang ) …

I wasn't aware DOSBox's core developers exclusively support Clang-based builds on OS X (happy if you can point me to that). Similarly, I wasn't aware the core developers have declared gcc as /not supported/ on OS X. Clang is not the only compiler that Apple has ever shipped. They used gcc long …

Oh.. interesting. They might have mangled it with their non-standard language extensions prior to getting clang underway. As I mentioned earlier that's exactly what happened. Their headers have always been designed to only work with their compiler, not sure why you're going to the effort of setting …

I believe Apple's version of gcc (back when they used to use it instead of clang) handles these files fine, the problem is an external build of gcc is being used instead. It's the classic problem of having to use apple's stuff to build for their platform.

You might want to check why configure is not enabling the dynamic_x86 core for all those builds.
