[Issue] Stack overflow error when calling dataAcquisition.setTwistChannelsUserCalibrationFactors

With the following main file main.cpp

Two behaviours appear when pressing "k" which starts dataAcquisition.setTwistChannelsUserCalibrationFactors:

• The first one : stack overflow error

• The second one : No stack error but terminal freeze.

Note: for a given flash, the behavior (stack error/overflow) is always the same. To trigger the other error, you must reflash the target and the error will eventually change.

• When using debugger, it is possible to enter several gains (not always the same count) until overflow error. An overflow error will invariably occurs. Note that the error won't occur at the same line of the code with debugger than without. With debugger it is on line 309 of shield_channels.cpp, in the function _shield_channels_get_calibration_coefficients:

Note that the code started to print the beginning of the line before crashing:

printk("%s %s applied will be : %f\n", physicalParameter, gainOrOffset, parameterCoefficient);
