Comment (by MarcusCalhoun-Lopez):

 Calling Fortran subroutines from C functions is a tricky business,
 especially when strings are passed between them.\\
 The last release of PGPOT was almost eight years ago, so GCC 8 was never
 tested.

 The problem seems to be when {{{cpgmtxt}}} is called more than once from
 different functions.\\
 I have no idea why this might be the case, but I will patch the demo
 program to call {{{cpgmtxt}}} only once.

 I believe that is the best we can do without a great deal of time and
 effort.
