7 years ago i think the main problem is you are building with the original SDK from espressif. Would you mind using esp-open-sdk or esp-open-rtos? i think you need full libgcc and not just the buggy espressif stuff.

5 years ago esp-open-sdk and esp-open-rtos are almost dead, whereas original ESP8266_RTOS_SDK is tending to regular releases and fixes.
A lot of time has passed since I created this issue. I will try to update ESP8266_RTOS_SDK and test again.
Hi, when I tried to build simple mongoose example for ESP8266 I faced with errors during linking. This errors looks like they related to stdlib. See my build output and makefile below:
