The problem is that this memory needs to be allocated up-front. All this message means is exactly what it says - the default amount is not sufficient and you need to change it in the build settings for the source file that builds your PCH, adding /Zm123 to the advanced compiler settings field there, or globally for your project.

Hmm, right. Maybe it's time for MS to increase the default. :p
The default is 75 MB on x86 (and 750 MB on x64), which is a fair amount of memory. Including all STL headers in VC10 SP1 consumed only 29.3 MB when I last measured it.
This has been increased to 83 MB in VC11 as of right now.
In one of the projects I'm working on, /Zm is at a comfortable 350 MB. This of course is mostly due to putting any stable third party library used in the PCH, which while nice from a compile-time cost perspective, makes IntelliSense keel over and die. -- Lars Viklund | zao@acc.umu.se
