Summary0031628: Configuration - Visual Studio 2019 compiler hangs on building 32-bit target
DescriptionUsers have reported the issue with VS2019 building 32-bit targets: [^]

The bug has been confirmed by MSFT and should be expected to be fixed in the next VS2019 update: [^]

Let see how soon it will be fixed and consider pushing one of available workarounds in case if it will come later than OCCT 7.5.0 release.
Steps To ReproduceBuild OCCT with MS Visual Studio 2019 in "Release" configuration of "Win32" platform with Whole Program Optimization disabled (it can be enabled with /GL command line key for compiler and /LTCG one for linker). The process of compilation is endless.

As for the workaround suggested by MSFT, __declspec (noinline) should be added before the declaration of the method NCollection_Vector::Iterator::Differ().
