--- Comment #5 from Dave Flogeras <dflogeras2 at gmail dot com> --- Definitely, this project is my testbed for playing with new C++ features on a STM32F4 micro. I also checked the ChibiOS (the RTOS I use) and it has always had -fsingle-precision-constant defined (well for all versions I have used in the past year). Certainly mysterious, maybe Gentoo was patching it.. I mean it has to be deterministic after all.
