Issue With std::function (and lambdas) With gcc and arm
This specific bug has caused be much pain when cross-compiling C++ code for the Zynq 7020 SoC (which has ARM A9 processors on-board). This caused software to seg fault for not good reason. It appeared when trying to use a captured this inside of a lambda function.
Code To Cause Issue:
The print to
std::cout causes the bug to occur. Other, non-stream operations will likely cause a similar issue
Effects: Effects GCC v6.2.0, possibly others.
Workaround: Either compile with only -O0 or -O1 level optimizations, or add the gcc compiler flag -fno-schedule-insns2 (which disables instruction scheduling).
