Trying to compile lib\mpl\example\fsm\player.cpp, DM 8.39 locks up, have to
3-finger it each time. The crash occurs early in the compilation, probably the
preprocessor:  if I set output to verbose, it crashes with only the first line
on the output window.

When I first open DM and it re-parses, it gives tons of preprocessor warnings.
Standard boost header headers, such as,
















now result in a warning at each line, about illegal characters following a
preprocessor directive.

Also, the following STLport file line, which looks to me quite normal,



gets a warning: Encountered preprocessor #error directive

(wxWindows example still compiles OK.)

Could you make a 3 line source file that causes this?

Trying to...  For now I've copied the player project to one clalled 'crash';
verified that Build crashes, and then found that the compiler seems to have
"crash memory"! --i.e.:  If I comment out all code, it stops crashing on Build;
but once I un-comment enough so that it crashes again, re-commenting the last
line commented-out does not prevent crashing.  I am NOT using pre-compiled
headers, by the way.

In more detail:

In crash.cpp (copy of player.cpp), I insert #if 0 / #endif around all code and
put a trivial main(), and it builds ok.  Then I move my #if 0 down testing that
it still compiles.
Once class 'player' is in, I get a link error I never had before (but it still
does not crash), namely:

sc crash.cpp -mn -C -WA -S -3 -a8 -c -gf -D_CONSOLE=1
-IG:\dm\STLport-5.0-1031\stlport -IG:\boost-1.30.2 -IG:\boost-1.30.2\boost\mpl
-IG:\boost-1.30.2\libs\mpl\example\fsm -IG:\dm\include -ocrash.obj 
link /CO /NOI /DE /NOPACKF /XN /NT /ENTRY:mainCRTStartup /BAS:4194304 /A:512
 crash.LNK 
Error: G:\player\crash.OBJ(crash)  (10864400): Symbol Undefined
?throw_exception boost  YAXABVexception std   Z (void cdecl
boost::throw_exception(exception::std const &))
Lines Processed: 41452  Errors: 1  Warnings: 0
Build failed

The compliler still won't crash on build, though, while function main() looks
like,

int main()
{
player p;
#if 0
p.process_event(player::play_event());
p.process_event(player::pause_event());
p.process_event(player::play_event());
p.process_event(player::stop_event());
#endif
return 0;
}


But once I move the #if 0 down one more line, un-commenting one of the
p.process_event(..) lines, Build locks up: app not responding. And even though I
have output set to verbose, all that shows in the output window is the
compilation command.

Sorry I can't give you better help than this, but I'm no wiz hacker;  and I'm
having to reboot windows every so many crashes.

Cheers!

Got it down to 3 lines!

int main() {
return 0;
}

DM++ 8,39 crashes and burns.

Though this only happens when I start from a project that is a copy of
player.cpp, and *after* it has crashed: Even stripping down the file to this
level it continues to crash the compiler.  I'll make a zip of the project's
folder and email it to you.

Cheers!
