As an aside I do get this issue with a VS2017 x64 debug built but NOT with a VS2019 x64 debug build so looks like something has been improved.
TLDR;
The root cause of the problem seems to be that when the compiler does not optimise the code the compilation fails with the "exceeded object file format error". The /Gy flag is not the cause instead it's the use of /Od (don't optimise to make debugging easier) and the lack of /O1 or /O2.
The command line below are the standard options before applying this fix.

/bigobjas per this PR or by replacing/Odwith/O1or/O2. The/bigobjfix is the right option since it will keep the object files in an unoptimised state and more suitable for debugging. - MarcoFalke merged this on Jun 20, 2019
