mjson unit_test failed.

I run the unit_test.c in arm clang. test_printf fail because "%M" point to jsonrpc_print_methods.

Care to share the output?

I have added an armlinux target which builds and tests on aarch64 linux - and tests pass:

make -C test armlinux

What hardware are you using? Is that a raspi or cortex-m device?

My hardware is stm32f103 and mdk IDE, compiler is armclang 6.

Thank you @tercelcn . Is there any chance to try it with GCC, just to narrow down the issue to armclang?
