Another way to fix it might be to change the return type of
GetCountString() from "const char*" to "string",
and change the value() call to
countOutp->value(GetCountString().c_str()).
The lifetime of the temporary string will then live
long enough through the return of the function to
reach value() before it gets deallocated.
Assuming value() makes an internal copy of the string,
all should be good, and this avoids the need for a
reentry-unsafe static variable in the function.
