Calling free(foo); free(foo); is not legal and may result in anything, including
pink smoke on top of your screen.
free(foo); free(foo); however is no problem as you may catch it vua libumem.
A real problem is fclose(fp); fclose(fp);
It does not harm on Solaris but it results in a free(foo); free(foo); call
on Linux although Linux did mark *fp to be closed already. This is something
that happened in SCCS before I fixed it and there is no way to detect it
on Solaris.
