I build it myself with your instruction. It worked well for a while, but after 2 days suddenly stopped with this message.

I did searching and found these, but not so helped yet.

Any suggest?

What's your build option?

[cryptozeny]

I just followed yours.

./autogen.sh # only needed if building from git repo
./nomacro.pl # in case the assembler doesn't support macros
./configure CFLAGS="-O3" # Make sure -O3 is an O and not a zero!
make

FYI at mining CPU temperature is 67 C (with cooling fan) It's good.
