Hi, When I try to call a function from GDB , the program being stopped at the end of main(), i always get a SIGILL: Program received signal SIGILL, Illegal instruction. 0xf00000 in ?? () the 0xF00000 adress is always the same It's on a i386 PC, i tried with printf or others functions. Thanks -- Fabrice Gautier fabrice_gautier@sdesigns.com
