Some distros (Ubuntu at the very least) +# have it enabled by default. +# +# gcc already optimizes some printf calls to call puts and/or putchar. When +# _FORTIFY_SOURCE is enabled and compiling with -O1 or greater, then some +# printf calls will also be optimized to call __printf_chk (in glibc). Any +# printfs which get redirected to __printf_chk are then no longer synchronized +# with printfs that go through mp_printf. +# +# In MicroPython, we don't want to use the runtime library's printf but rather +# go through mp_printf, so that stdout is properly tied into streams, etc. +# This means that we either need to turn off _FORTIFY_SOURCE or provide our +# own implementation of __printf_chk. We've chosen to turn off _FORTIFY_SOURCE. +# It should also be noted that the use of printf in MicroPython is typically +# quite limited anyways (primarily for debug and some error reporting, etc +# in the unix version). +# +# Information about _FORTIFY_SOURCE seems to be rather scarce.
