Hi Valgrind community, I have 2 different boards running QNX 6.5 and mounting the exact same file system. One board is based on an NXP iMX53 SoC and the other one on a Texas Instrument AM3352. Since both SoC share the same instruction set (Cortex A8 - amv7le), they can run the same binaries.
However, whereas Valgrind 3.10.1 is working perfectly on the iMX53, it crashes on the AM3352 : pendant:/bin>/usr/bin/valgrind --tool=memcheck --allow-mismatched-debuginfo=yes --extra-debuginfo-path=/usr/lib/debug/ echo ==1863697== Memcheck, a memory error detector ==1863697== Copyright (C) 2002-2013, and GNU GPL'd, by Julian Seward et al. ==1863697== Using Valgrind-3.10.1 and LibVEX; rerun with -h for copyright info ==1863697== Command: echo ==1863697== ==1863697== ==1863697== Process terminating with default action of signal 11 (SIGSEGV): dumping core ==1863697== Bad permissions for mapped region at address 0x245C ==1863697== at 0x1E4CC: mprotect (mprotect.c:33 in /proc/boot/libc.so.3) ==1863697== by 0x25B03: _band_get_aligned (band.c:450 in /proc/boot/libc.so.3) ==1863697== by 0x77383: ???

I am clueless, I don't understand how it can work on iMX53 and fail on AM3352 with the same file system (same binaries, same libs, same scripts, same conf ...). Does somebody have an idea ?
