Sorry, I am wrong. It did not pass for 64-bit run. It looks like the "make biarch-test" can pass this test though. You can try both, ibm-js20-02.lab.bos.redhat.com ibm-js22-03.rhts.bos.redhat.com > Or, could you please run the trivial program below on that machine? # gcc read.c -o read # ./read ptr: 0x10010bf0 00100000-00120000 r-xp 00000000 00:00 0 [vdso] 10000000-10010000 r-xp 00000000 fd:00 48844 /root/read 10010000-10020000 rw-p 00000000 fd:00 48844 /root/read fffa7c70000-fffa7e30000 r-xp 00000000 fd:00 5741 /lib64/libc-2.10.90.so fffa7e30000-fffa7e40000 r--p 001b0000 fd:00 5741 /lib64/libc-2.10.90.so fffa7e40000-fffa7e60000 rw-p 001c0000 fd:00 5741 /lib64/libc-2.10.90.so fffa7e60000-fffa7e70000 rw-p 00000000 00:00 0 fffa7e70000-fffa7ea0000 r-xp 00000000 fd:00 5734 /lib64/ld-2.10.90.so fffa7ea0000-fffa7eb0000 r--p 00020000 fd:00 5734 /lib64/ld-2.10.90.so fffa7eb0000-fffa7ec0000 rw-p 00030000 fd:00 5734 /lib64/ld-2.10.90.so ffff06c0000-ffff0810000 rw-p 00000000 00:00 0 [stack] # gcc -m32 read.c -o read # ./read ptr: 0x100004fc 00100000-00120000 r-xp 00000000 00:00 0 [vdso] 0fe20000-0ffd0000 r-xp 00000000 fd:00 5827 /lib/libc-2.10.90.so 0ffd0000-0ffe0000 r--p 001a0000 fd:00 5827 /lib/libc-2.10.90.so 0ffe0000-0fff0000 rw-p 001b0000 fd:00 5827 /lib/libc-2.10.90.so 10000000-10010000 r-xp 00000000 fd:00 48844 /root/read 10010000-10020000 rw-p 00000000 fd:00 48844 /root/read f7df0000-f7e00000 rw-p 00000000 00:00 0 f7e00000-f7e30000 r-xp 00000000 fd:00 5733 /lib/ld-2.10.90.so f7e30000-f7e40000 r--p 00020000 fd:00 5733 /lib/ld-2.10.90.so f7e40000-f7e50000 rw-p 00030000 fd:00 5733 /lib/ld-2.10.90.so ff9c0000-ffb10000 rw-p 00000000 00:00 0 [stack] Thanks, CAI Qian
