I've been able to compile a 64bit version of MAME up until 0.145u4. Now I receive a compiling error. I am still able to compile a 32bit version (virtual machine with same OS and gcc version as below except 32bit). Thanks for any assistance.

OS: Ubuntu 10.10 64bit
gcc (Ubuntu/Linaro 4.4.4-14ubuntu5.1) 4.4.5
I get the error running make or make -j5.
Error:

Hi,

That error indicates one of the following things:

1) Your RAM is marginal; run memtest86 for a few hours to check
2) Your computer is overclocked too high and/or dust buildup is preventing proper cooling
3) That GCC version is buggy

The file does build fine for other Ubuntu users so it's more likely 1) or 2) assuming your packages are up to date.

Updated GCC (not a package, had to manually compile) and error solved. Thanks for the response/answer.

I hit this problem as well: it is most likely a gcc 4.4 bug
