LWIP from SDK 1.4 bid from src is restarting ESP8266

[osteinjr]

Hi , I need help.

I'm compiling the RTOS SDK 1.4 lwIP . When I use the version that I compiled the ESP8266 is restarting when I connect by the SOFT Interface. The same does not occur with lwIP original that is in the lib folder .
Steps I'm doing :
1 ) enter the lwIP folder SDK
2 ) make
3 ) cp my build lib liblwip.a to SDK lib folder (overwrite)
4 ) compile the driver_sample
5 ) record the firmware
