Hi @soramame21

can you please specify the compiler version? I would almost suspect a compiler bug in this case.

Hi @JanneKiiskila

I am facing same problem by online compiler (armcc 5.06 build 61, K64F + ESP8266 WiFi).
But, I didn't have any issue by mbed-os-5.3.6 release.

Hi @JanneKiiskila

Very sorry for delayed reply. here is my compiler versions.
arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors) 4.9.3 20150529 (release)

Component: ARM Compiler 5.06 update 4 (build 422)

This has been verified that it works fine for ARMCC with latest mbedOS 5.4.3 on K64F, please retest and if its still not working, I suggest try with https://github.com/ARMmbed/mbed-os-example-sockets to verify connectivity.
