Compiling Chapel with gcc 12.1 in CHPL_DEVELOPER=true mode has been reported by the GASNet team to turn up errors in truly ancient (circa 2005) code. This issue captures the task of getting the code building cleanly with gcc 12.1.

config.c: In function 'aParsedString':
config.c:92:22: error: the comparison will always evaluate as 'true' for the pointer operand in 'equalsSign + 1' must not be NULL [-Werror=address]
   92 |   if (!equalsSign || !(equalsSign + 1)) {
      >                      ^
