Don't even more but it is a rare case where I encounter mallopt usage?

Anyway here it is:

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <errno.h>

/* getpid(), geteuid()  */
#include <sys/types.h>
#include <unistd.h>

/* setgroups() */
#include <grp.h>

/* mkdir() */
#include <sys/stat.h>
#define MAXPATHLEN 256

/* waitpid() */
#include <sys/wait.h>

/* mallopt() */
#include <malloc.h>

#define SQUID_MAXFD 4096

/* autoconf.h */
/* Define if you have the mallopt function.  */
#define HAVE_MALLOPT 1

/* dlmalloc.c */
#define M_GRAIN   3    /* UNUSED in this malloc */
#define M_MXFAST  1    /* UNUSED in this malloc */

int Squid_MaxFD;		/* SQUID_MAXFD */

FILE *debug_log = NULL;

int
main(int argc, char **argv)
{
    int errcount = 0;
    mode_t oldmask;

    debug_log = stderr;
    if (FD_SETSIZE < Squid_MaxFD)
	Squid_MaxFD = FD_SETSIZE;

    fprintf(stderr, "nb_err: %d\n", errcount);
    /* call mallopt() before anything else */

#ifdef HAVE_MALLOPT
    fprintf(stderr, "  HAVE_MALLOPT \n");
#ifdef M_GRAIN
    /* Round up all sizes to a multiple of this */
    fprintf(stderr, " M_GRAIN seti: %d\n", M_GRAIN);
    mallopt(M_GRAIN, 16);
#endif
#ifdef M_MXFAST
    /* biggest size that is considered a small block */
    fprintf(stderr, " M_MXFAST seti: %d\n", M_MXFAST);
    mallopt(M_MXFAST, 256);
#endif
#ifdef M_NBLKS
    /* allocate this many small blocks at once */
    fprintf(stderr, " M_NBLKS set: %d\n", M_NBLKS);
    mallopt(M_NLBLKS, 32);
#endif
#endif /* HAVE_MALLOPT */

/*
    oldmask = umask(S_IRWXO);
 */

    return 0;
}

compile it with cmd:
gcc -o foo -l pthread foo.c

(the simple gcc -o foo foo.c do not present the pb;
neither gcc -static -o foo -l pthread foo.c [previously it makes a segv])

Thanks for your attention,
    Joel
