Follow-up Comment #21, bug #60016 (project octave):
I just lightly read the example from Qhull. But I *don't* see that they
initialize qh_qh in any way. The entire main () function is
int main(int argc, char *argv[]) {
int curlong, totlong; /* used !qh_NOmem */
int exitcode, numpoints, dim;
coordT *points;
boolT ismalloc;
qhT qh_qh;
qhT *qh= &qh_qh;
QHULL_LIB_CHECK /* Check for compatible library */
if ((argc == 1) && isatty( 0 /*stdin*/)) {
fprintf(stdout, qh_prompt2a, qh_version, qh_prompt2b);
exit(qh_ERRnone);
}
if (argc > 1 && *argv[1] == '-' && (*(argv[1] + 1) == '?' || *(argv[1] + 1)
== '-')) { /* -? or --help */
fprintf(stdout, qh_prompt2a, qh_version, qh_prompt2b);
exit(qh_ERRnone);
}
if (argc > 1 && *argv[1] == '-' && (*(argv[1] + 1) == '?' || *(argv[1] + 1)
== '-')) { /* -? or --help */
fprintf(stdout, qh_prompt2a, qh_version, qh_prompt2b);
exit(qh_ERRnone);
}
if (argc > 1 && *argv[1] == '-' && !*(argv[1]+1)) {
fprintf(stdout, qh_prompta, qh_version, qh_DEFAULTbox,
qh_promptb, qh_promptc, qh_promptd, qh_prompte);
exit(qh_ERRnone);
}
if (argc > 1 && *argv[1] == '.' && !*(argv[1]+1)) {
fprintf(stdout, qh_prompt3a, qh_version, qh_prompt3b);
exit(qh_ERRnone);
}
if (argc > 1 && *argv[1] == '-' && *(argv[1]+1)=='V') {
fprintf(stdout, "%s\n", qh_version2);
exit(qh_ERRnone);
}
qh_init_A(qh, stdin, stdout, stderr, argc, argv); /* sets qh->qhull_command
*/
exitcode= setjmp(qh->errexit); /* simple statement for CRAY J916 */
if (!exitcode) {
qh->NOerrexit= False;
qh_initflags(qh, qh->qhull_command);
points= qh_readpoints(qh, &numpoints, &dim, &ismalloc);
qh_init_B(qh, points, numpoints, dim, ismalloc);
qh_qhull(qh);
qh_check_output(qh);
qh_produce_output(qh);
if (qh->VERIFYoutput && !qh->FORCEoutput && !qh->STOPadd && !qh->STOPcone
&& !qh->STOPpoint)
qh_check_points(qh);
exitcode= qh_ERRnone;
}
qh->NOerrexit= True; /* no more setjmp */
#ifdef qh_NOmem
qh_freeqhull(qh, qh_ALL);
#else
qh_freeqhull(qh, !qh_ALL);
qh_memfreeshort(qh, &curlong, &totlong);
if (curlong || totlong)
qh_fprintf_stderr(7079, "qhull internal warning (main): did not free %d
bytes of long memory(%d pieces)\n",
totlong, curlong);
#endif
return exitcode;
} /* main */
It is also possible that Qhull authors provided incomplete example.
