...change_and_add. The problem is that the result read by ldrex is stored by the inline optimization on the stack for further use. However, as the atomically read variable is also on the stack and resides very close to this compiler-induced intermediate storage - the write hits the ERG. On Apple's A6X devices this reproduced consistently - the code entered a perpetual loop, as the str instruction at 0x52 caused the srtex at 0x56 to always fail and always return 1 and the following branch started it all over. Generating such code violates the ARM recommendation:"For these reasons ARM recomm...
