GNU 4.9 2014q4 SMT32F4 ChibiOS 3.0 supported?

[wizhippo]

Is anyone having success with this compiler?

I can compile the exact same project using the older 4.7 2014q2 and my project works but using this new version it works for a few seconds the ends up in the unhanded exception handler.

Are there some other compiler options that I should add beyond those in the makefile included with the demo's?

My project does use the cpp_wrappers

I used it on the STM32F4 demo and the test suite apparently ran successfully.

You may have problems caused by different optimizations, for example stack overflows.

I had c++project which was exhibiting the same behavior (launch, but hardfault under certain condition), only with gcc 4.9.

In my case, it was a bug in my code, chSysInit and halInit was called twice.

now all my project compile and run fine with 4.9 (chibios 2.6.7)
