What does this error means?
Can it be fixed?

I happens to me in WinXP compiling wxWidgets in the WX_2_8_BRANCH in the
revision 49563, but only if I add
-HP90 to the CPP flags.

If I take the -HP90 flag away the error stops and the compilation is succesful.

(Sorry I don't know any other way to reproduce the error.)

I added
# Standard flags for C++
CXXFLAGS = -HP90

...to the configuration file because the samples were not compiling, with an
out of memory error.

It means there is a potential overflow/wraparound issue in the way the 
compiler manages memory mapped file I/O. I suggest if it works without 
-HP90, then don't use it.

I changed another thing.

I set USE_EXCEPTIONS = 0
it was 1 previously.

Now everything compiles and runs correctly, even the Unicode builds, those
weren't working with exceptions enabled, no
matter what the -HP flag was. I had to add the -HP flag to be able to compile
samples, and take it away to compile the
library. Now that's no longer necessary.

Everything is nice and good. I will not enable exceptions again (I don't use
them anyway).
