My second try with clean compile. C:\Emulator\Mess\SVN\Bin\mess>make TARGET=mess Compiling src/mame/drivers/megadriv.c... src/mame/drivers/megadriv.c: In function 'void driver_init__32x(running_machine* )': src/mame/drivers/megadriv.c:6577: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See < http://gcc.gnu.org/bugs.html> for instructions. make: *** [obj/windows/mess/mame/drivers/megadriv.o] Error 1 Can it be, something wrong with my GCC 4.4.3 20091223 version ?

you might have stopped compilation during first run, ending up with a half-compiled megadriv.o
try deleting it from the obj/windows/mess/mame/drivers/ directory and restarting compilation
current svn compiles fine Thank you to try to help me.  My obj/windows/mess/mame/drivers/ directory is and was empty.

I got the same error today on a clean compile, it has happened to very many people, however I'm told we all have faulty pcs.
One suggestion is to not use the -j option, but if that doesn't fix it, go to mess/drivers/genesis.c, mame/includes/megadriv.h, and mame/drivers/megadriv.c and change the reference of DRIVER_INIT(_32x) to x32x. That always works. No idea why though.
If you get a segfault while compiling tms57002, open the file it complains about (tms57002.c), look for the first occurence of "cycles > 0" (without the quotes) (it's a IF statement) and enclose it in ( ) - so it looks like (cycles > 0) .. this always works too, again no idea what difference it could make.

Not faulty pcs, its just that the newer mame/mess build toolkit mingw64 version has some nasty extremely-hard-to-track compiler bugs which are especially prevalent in the 32 bit version but don't affect the 64 bit version much if at all.
They also, for some reason, cause much more problems on winxp than on win7 or vista, and I have no idea why...

More accurately, there's an intermittent compiler bug on XP (a 10 year old operating system) which doesn't occur on 32 or 64 bit versions of Vista or 7 (or at all on Linux/BSD/Mac). The same compiler bug also occurs on systems which are overclocked or have faulty RAM.
Anyway, Firewave was pissed because it wasn't happening for a while, so now he can go to work.

The compiler can tell you faster and easier than us - if it generates a new error, you forgot something Also, if you don't normally use -j, adding it can sometimes bypass the initial error.

that is just a workaround which might work or not on your computer, not a real fix. e.g. the unmodified code compiles perfectly on my winxp computer. this is a subtle compiler problem which we hope to solve sooner or later.
notice that someone else used a different workaround consisting of changing the order of some constant (without need of renaming any 32x item).
Kale reported that compiling with lower case
make target=mess
fixed as well the issue in his computer, but I never got the error, so I don't know if it would work for everyone.
