Follow-up Comment #4, bug #59831 (project lwip):
By "Another tasks was executed between this line 1328 and line 1382", I mean
that FreeRTOS can switch tasks when the time allowed for one tasks is elapsed
: https://www.freertos.org/implementation/a00005.html
Always talking about FreeRTOS, yes, there is a way to prevent tasks switching
by surrunding the porting with taskENTER_CRITICAL() and taskEXIT_CRITICAL() :
