Hm, probably the same reason as #84. Interesting that it only happens with Release builds. At the very least this doesn't happen with Visual Studio, but it may be that the immediate parsing code is relying on some undefined behavior somewhere...
This is likely to be the function where it goes wrong: https://github.com/Kingcom/armips/blob/master/Archs/ARM/CArmInstruction.cpp#L31
Called from here: https://github.com/Kingcom/armips/blob/master/Archs/ARM/CArmInstruction.cpp#L213

I'll have to try it out in a Linux/Ubuntu VM later to see if I can reproduce it there. If you want, can you maybe post the assembly code generated for getShiftedImmediate, or try to disable optimizations for it and see if it helps?
