I got an error of "Illegal instruction" with the debug version.
I complied the v8 code(v3.19.0) with command: make android_arm.debug
armv7=false. Then run it on android phone, after a while(about 40s) it came
out such an errror:
> [1] Illegal instruction ./cctest test-hashing
>
>
> I got some info while it came out "Illegal instruction" with the debug
version:
> Program received signal SIGILL, Illegal instruction.
