Current consumption difference between GNU and IAR builds

[Robert]

I am experiencing a difference in current between the example program during advertising between a IAR compilation and a GNU compilation.

The differences appear to be significant in a range of 10x more power for the GNU during advertising.

Seeing the numbers would also be helpful, they can some times indicate what is running or not.
As Turbo is saying, the choice of compiler shouldn't have such a big impact on current consumption. If you see a huge difference I am inclined to think that the power management is not working properly with one of the compilers.
