Hi,
Thanks Wan Mohd Fairuz Wan Ismail for your reply.
I am running valgrind on ARM based freescale iMX25 3 stack board.
Linux version 2.6.31.
I have moved the program more a accessible directory but result is same.
starce log :
munmap(0x401c000, 8192) = 0
stat64("/lib/ld-2.5.so", {st_mode=S_IFREG|0755, st_size=157500, ...}) = 0
open("/lib/ld-2.5.so", O_RDONLY|O_NOFOLLOW) = 3
read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0(\0\1\0\0\0\340\7\0"...,
