Anytime I got the megadriv.c error recently, I found that running make without any -j flag allowed me to complete compile. Not sure why, though.

What could it be? SVN r7890, Windows, 32-bit, MinGW (GCC 4.4.3) downloaded from mamedev.org, clean compilation using either make TARGET=mess or make TARGET=mess tools I get this error:
Compiling src/mame/drivers/megadriv.c...
src/mame/drivers/megadriv.c: In function 'void driver_init_x32x(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
SVN r7890 compile is working for me (GCC 4.4.3 32-bit, WinXP Pro SP3) make TARGET=mess make TARGET=mess tools You really make a clean compile ? Try to make all (src + obj)new. Meanwhile, you can use bobz daily SVN build .

I fixed this in r7884, by changing _32x to x32x, seems the compiler doesn't like the underscore.

Uhh, no. That error means your RAM is faulty and/or overheated. Changing random things about the code (e.g. the underscore) may make it succeed for a time, but it's not actually fixing the problem and it makes the code uglier. (This is why building without -j helps - the CPU is working less and the system is cooler).

Hi I had the same problem. But it only started after moving to 0.137. 0.136 didn't had this problem.

On my Pentium 4 HT the problem, which persisted when building without -j, has been solved by adding -j2.

I'm not quick to rule out genuine bugs in GCC these days....

ICEs that only happen sometimes on some machines are hardware faults 9 times out of 10.
