Enabling --gnu in uVision causes SD crash

Hello,

We are porting legacy application to the nrf52840. We are using Keil uVision 5.

The legacy code is using some gcc ideas and extensions so we are forced to use --gnu as an argument for the compile.

Enabling the --gnu causes the Softdevice (140 v 6.0.0.0) to crash upon activation.

To double check I have compiled the ble_app_hrs_freertos from the nrf sdk (v 15) with and without the --gnu compiler flag.

With the --gnu compiler flag the ble_app_hrs_freertos  application crashes but without the --gnu flag it runs fine.

Any ideas on how I can get code compiled with the --gnu flag to work with the softdevice?
