Resolution:
The problem happens on PA-RISC1 HP-UX machine only. This is
fixed in Hawk 3.1.4 and Hawk 4.01. To see the version of your PA-RISC architecture on your machine, follow the attached information.

********** checking on  the PA-RISC version ****
$ getconf CPU_VERSION

     will output a decimal number.
     convert this number to hexadecimal and check in sys/unistd.h

     /usr/include/sys/unistd.h
     #  define CPU_PA_RISC1_0  0x20B /* HP PA-RISC1.0 523 */
     #  define CPU_PA_RISC1_1  0x210 /* HP PA-RISC1.1 528 */
     #  define CPU_PA_RISC1_2  0x211 /* HP PA-RISC1.2 529 */
     #  define CPU_PA_RISC2_0  0x214 /* HP PA-RISC2.0 532 */
