Subj: A bug in Sozobon Optimizer ?

      The following program gives me 2 differents results when compiled
with sozobon C. Without optimization , I get the correct result:
       01-09-89 06:25
and compiled with the -O flag, I get
       01-09-89- 06:2
      Has someone found and fix such "features" in the optimizer?

#include <osbind.h>

main()
{
      char txt[10];

      convtime(0x1321,0x3333,txt);

      printf("%s\n",txt);
}
convtime(date,time,p)      /* gives date & time on the form DD-MM-YY HH-MM */
int date, time;
register char *p;
{
      int dt[5];
      register int i;
      register char *t;

      dt[0]=date & 0x1f;
      date >>=5;
      dt[1]=date & 0x0f;
      date >>=4;
      dt[2]=(date & 0x7f) +80;
      time >>=5;
      dt[4]=time & 0x3f;
      time >>=6;
      dt[3]= time & 0x1f;
      for (i=0; i<5; i++)
            dt[i] = ((dt[i]/10 << 8) | dt[i]%10 ) | 0x3030;
      t=(char *)dt;
