Warning: size of symbol `bstate3_' changed

I was recompiling CMAQv5.3.2 after a small correction aqchem.F (changed maximum iterations from default 60,000 to 100,000) using ‘make clean’ followed by ‘make’ under BLD directory when I got this last line on my standard output:

ld: Warning: size of symbol `bstate3_' changed from 14835740 in pshut3.o to 14835744 in /proj//MYLIB_PROJ/cmaqv5.3.2_17oct2020/CMAQ_Project_17oct2020/lib/x86_64/intel/ioapi/lib/libioapi.a(initblk3.o)

The compilation process did create a CCTM.exe file but I wanted to ask if this Warning needs further investigation.

This seems to be a spurious warning that can happen when parts of the system are built with different compile-flags or compiler-versions (from the same vendor)
