Forgive me if I should know this but I notice Compiler Explorer pgm output shows only the last byte of the value C++ pgm returns though the assembly shows a different 4-byte value being returned.

Wandbox does the same: https://wandbox.org/permlink/llqGvLRGw2sSHnhT

But running the exe on Windows after compiling with GCC on MinGW returns the complete value.

Is this an OS thing: Windows v Linux? Sorry me no Linux.
