C3859: virtual memory range exceeded for PCH

I get this error message from time to time (not every time). I am compiling (EDIT: sorry, I didn’t explain here: I really meant "rebuild") my project in mixed mode. And Visual Studio tells me to "recompile with the command line option" -Zm114 "or more." In principle, there is no problem, I just do as VS says.

But there are currently two problems:

  • Why doesn't this happen every time I rebuild? If I understand correctly, the compiler ran out of memory when compiling my project. So if I do a reconnection that clears all previous work, should it not be over the next time if I don't change anything?

  • To be safe, I already specified a value of 120 for Zm (i.e. Zm120) in all configurations of this project. Why am I getting an error with this lower value? Or is suggested value 114 just a wild guess of VS?

Unsurprisingly, Visual Studio broke out very much because of this, in particular, due to numerous errors C3859during the build.

When parsing the project’s configuration for Inherit, this value was fixed.
