Hi yzt,

Many thanks for getting back to me, your help is much appreciated.

I tried switch /ZmXXX with a couple of different values for XXX, this
seems to have no effect on the problem and still the VC8 Release build
crashes with C1060.

The documentation says that /Zm "Determines the amount of memory that
the compiler allocates to construct precompiled headers".  Can you
give a little more detail on how you think that C1060 could be avoided
in this case by changing the memory allocation for precompiled
headers?

The example I provided in the original post is a sole cpp file, I
haven't myself created any headers, precompiled or otherwise.  The
code #includes various headers from STL and boost, are you saying that
those #includes are picking up precompiled headers such that the
behavior of the build could be influenced by /Zm?

Thanks,
Eric
