warning on var totalCount compile on mac venture clang

[jmscott]

just a heads up.

compile under mac venture clang gives this warning:

 src/rumdatapage.c:1063:8: warning: variable 'totalCount' set but not used [-Wunused-but-set-variable]
    int                     totalCount = 0;

the warning appears to be incorrect, as totalCount is incremented in scope at lines: 1103, 1115, 1137, 1152.
no sure what's up.

the compiler version is Apple clang version 14.0.3 (clang-1403.0.22.14.1) and compile core pg15.3 with no issues. the ventura version is Darwin tmonk 22.4.0 Darwin Kernel Version 22.4.0: Mon Mar 6 21:00:17 PST 2023; root:xnu-8796.101.5~3/RELEASE_X86_64 x86_64 i386 Darwin.
