Re: std::atomic misbehaving on armeabi

[David Turner]

NDK r7 didn't come with GCC 4.6, what are you using exactly?

Hello,

I'm using android-ndk7 (with G++ 4.6) and am building a simple C++11 app targeting armeabi.

I'm noticing some issues with std::atomic: the operator= misbehaves.

Look to the following piece of code

std::atomic<void*> atomicPtr;

void *ptr = (void*) 0x12345678;

atomicPtr = ptr;

logger << (void*) ptr << ", " << (void*) atomicPtr;

I would expect it to print "0x12345678, 0x12345678", but instead I get unexpected results (like "0x12345678, 0xbede67a0").

I'm prone to think it's a bug with std::atomic, although couldn't look further into it.
