Surely there is some mistake here?  FILE*s returned by popen() are ONLY
supposed to be closed by pclose().  To quote the manual:
     A stream opened by popen should be closed by pclose, which
     waits for the associated process to terminate and returns
     the exit status of the command.
NEVER close popen()ed files with fclose()!
