I am seeing an out of memory message of:

"cc1plus.exe: out of memory allocating 65536 bytes"

when compiling code using mingw-64 from gcc-4.8.1, gcc-4.8.2, gcc-4.8.3, 
gcc-4.9.0, and gcc-4.9.1. Nor is this just a mingw-64 problem as I am 
seeing the same error when compiling the same code with mingw and gcc-4.8.1.

Strangely this error does not occur when compiling the exact same code 
using versions from mingw of gcc-4.3.0 through gcc-4.7.2.

The code is heavily preprocessor code for my VMD library, which also 
depends on the Boost PP library. In other words the code is almost 
entirely involved with testing macro expansions in the libray. As a 
piece of related information, which may not be very relevant, the latest 
clang and versions of vc++ from vc++8 through vc++12 do not exhibit any 
out of memory errors.

It seems gcc has regressed in some way starting with version 4.8.1 in 
its handling of memory allocation. Is this a known problem with with 
these latest gcc releases ? Is anyone involved with gcc trying to fix 
the problem if it is known ? Or might this just be a problem in Windows 
with mingw and mingw-64 implementations of the latest gcc ?

The code in question is highly complicated, as befits an advanced macro 
programming library like VMD, so it would be very difficult to reproduce 
it in some simpler form. But the fact that it occurs in the latest 
version of gcc-4 but not in the earlier versions suggests something that 
has been done wrong and might already be known about.

I am compiling under Windows 7 Ultimate with 8 GB of real memory, so I 
do not think this has anything to do with my hardware itself.
