amrbekhit opened a new issue #1653: config functions don't work when the string is a constant
URL: https://github.com/apache/mynewt-core/issues/1653
 
 
   Some of the config module functions (e.g. conf_get_value) don't work when the string is a const. Because these functions internally use strtok_r, which modifies the original string, if the string passed into the function is a const (such as a string literal), the function will fail to tokenize the string properly. The workaround in the user code is to copy the config name to a temporary variable and pass that into the function.
   
   Perhaps it might a good idea to have the config functions do this themselves internally, as it's not obvious in the documentation that this is the behaviour and it's a difficult bug to diagnose.
