Hi, I am getting the following error when i try to run valgrind-3.2.3 on ppc machine. Can anyone please let me know if there is any problem with the way i built valgrind or any other issue. (i used the following to build valgrind sources /configure --host=powerpc-linux --disable-tls make make install) cat /proc/cpuinfo error log: bash-2.05# ./valgrind /bin/date ==3468== Memcheck, a memory error detector. ==3468== Copyright (C) 2002-2007, and GNU GPL'd, by Julian Seward et al. ==3468== Using LibVEX rev 1732, a library for dynamic binary translation. ==3468== Copyright (C) 2004-2007, and GNU GPL'd, by OpenWorks LLP. ==3468== Using valgrind-3.2.3, a dynamic binary instrumentation framework. ==3468== Copyright (C) 2000-2007, and GNU GPL'd, by Julian Seward et al. ==3468== For more details, rerun with: -v ==3468== ==3468== ==3468== Process terminating with default action of signal 11 (SIGSEGV) ==3468== Bad permissions for mapped region at address 0x4024BF4 ==3468== at 0x4024BF4: ??? ==3468== by 0x40100E4: (within /lib/ld-2.2.5.so) ==3468== ==3468== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0) ==3468== malloc/free: in use at exit: 0 bytes in 0 blocks. ==3468== malloc/free: 0 allocs, 0 frees, 0 bytes allocated. ==3468== For counts of detected errors, rerun with: -v ==3468== All heap blocks were freed -- no leaks are possible.

Please ignore cat /proc/cpuinfo above, i meant giving the following information: file valgrind valgrind: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1 (SYSV), dynamically linked (uses shared libs), not stripped
Can you please add the output of valgrind -v /bin/date, as requested on http://www.valgrind.org/support/bug_reports.html ?
Bart, gdb is not currently available, i will try to get that and let you know the trace. I have made the following information for now: Please Let me know if this helps. logs: bash-2.05# ./valgrind --vex-guest-chase-thresh=0 --trace-flags=10000000 --trace-notbelow=999999 /bin/date ==4709== Memcheck, a memory error detector. ==4709== Copyright (C) 2002-2007, and GNU GPL'd, by Julian Seward et al. ==4709== Using LibVEX rev 1732, a library for dynamic binary translation. ==4709== Copyright (C) 2004-2007, and GNU GPL'd, by OpenWorks LLP. ==4709== Using valgrind-3.2.3, a dynamic binary instrumentation framework. ==4709== Copyright (C) 2000-2007, and GNU GPL'd, by Julian Seward et al. ==4709== For more details, rerun with: -v ==4709== ==== BB 0 (0x40100D4) BBs exec'd 0 ==== ==== BB 1 (0x4001D60) BBs exec'd 1 ==== ==== BB 2 (0x4001DA4) BBs exec'd 2 ==== ==== BB 3 (0x4024BF4) BBs exec'd 3 ==== ==4709== ==4709== Process terminating with default action of signal 11 (SIGSEGV) ==4709== Bad permissions for mapped region at address 0x4024BF4 ==4709== at 0x4024BF4: ??? ==4709== by 0x40100E4: (within /lib/ld-2.2.5.so) ==4709== ==4709== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0) ==4709== malloc/free: in use at exit: 0 bytes in 0 blocks. ==4709== malloc/free: 0 allocs, 0 frees, 0 bytes allocated. ==4709== For counts of detected errors, rerun with: -v ==4709== All heap blocks were freed -- no leaks are possible.

Any further info on this? I am inclined to close it unless more info appears -- there is not enough here to establish the problem.
