@Christoph-Hart I’m a new HISE user - I love it. I’ve been experimenting and compiling VSTs to try things out. I last built HISE shortly after the “fix compilation for real” commit 078a2487 from March 5 and it’s been smooth sailing.
I built HISE from fresh source to get in on this new serial killer agenda. I think it worked - I’m seeing fatal errors during plug-in compile that weren’t present before. 
Terminal log attached, with cap blocks added to bracket the new warnings and errors.
