Unity3d Mono Arm non-eating interrupt 33

It's not even now how many games are written by Unity3d.

Operation is very convenient, in unity to write a program, directly generated Android APK

But the inside is actually listening complex, for scripts generated in C # need to use mono to explain the execution

The Android app is running on the Dalvik Java virtual machine, which runs after two layers of runtime

But we're more "perverted" and we want to run the Unity program with Mono in Qemu-arm (host is x86)

The result is a problem.

Mono Error
Mono: * Assertion at mini-posix.c:382, condition ' sigaction (Signo, &SA, &PREVIOUS_SA)! =-1 ' not met

Plus log found to be a problem with settings   interrupts 33

Wrote a small program PNP5 direct intercept Interrupt 33 error

$ ld_library_path=./system/bionic_arm/system/lib./system/target_libc/system/bin/qemu-arm./system/bionic_arm/ System/bin/pnp5
Sigaction return-1

It is also an error to compile this program with GLIBC

Should be Ubuntu Linux don't let setup interrupt

But since Unity is so popular, it's not going to go wrong in arm phone testing

Using the NDK to compile this program, there is no error

So in Android Linux, interrupt 33 is allowed to be set

In addition, Unity-generated x86 lib can be run under Ubuntu Linux, so only the Mono-arm library is set to interrupt 33
