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.)

Can you give some more details; which version were you using of d mars, and what file were you compiling when the error ocurred
thanks

And the compilation dies on:
dmc -mn -c -cpp -odmc_mswd\baselib_dummy.obj -g -o+none     -D_WIN32_WINNT=0x0400 -D__WXMSW__  -D__WXDEBUG__       -

\pch_wxprec_baselib.sym  -HP90 ..\..\src\common\dummy.cpp
Internal error: ph 619
--- errorlevel 1



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).
