Strange, this bit_ref constructor is defined in the asn1_utils.h header file so it should be inlined. What compiler options do you use?
Run the following commands and provide the lines just before these errors that contain the compiler flags.

    touch ../srsue/test/upper/rrc_reconfig_test.cc
    make VERBOSE=1 rrc_reconfig_test

Alternatively you could try moving the constructor definition to asn1_utils.cc or a clean rebuild - remove the build directory and start from scratch.

Could you give me a link to the exact Debian or Raspbian image you have installed?
