Major milestone forward for HyperDbg supporting #Linux.

We've made a major progress on porting HyperDbg to Linux (still a long road ahead). Now the HyperDbg SDK can be compiled with GCC for both user/kernel modes on Linux.

More updates coming soon...👀

Apparently this issue is affecting others too. As we can't revert to older GH runner image versions, we will temporarily publish unoptimized release builds until MS pushes a fixed runner image. https://t.co/YBoViGFW5C https://t.co/FA0kerRJKR (2/2)

[RPCS3 @rpcs3]

Visual Studio 17.14.X compiler versions introduced a compiler optimisation bug, causing severe issues on RPCS3 such as missing game audio.

17.14.9 fixes it - we expect this version to be available on GitHub next week.

This is why there have been no builds for the last 4 weeks.

[Björn Ruytenberg @0Xiphorus]

We have received reports @HyperDbg's latest release shows unexpected behavior. As it turns out, this is due to a compiler optimization bug in Visual Studio 17.14.8 and 17.14.9. We have pushed a temporary workaround fixing the build. Thanks for reporting! (1/2)

[Sinaei @Intel80x86]
