Re: [Valgrind-users] Valgrind crash on Texas Instrument AM3352 (armv7le) and QNX

Run valgrind with "-d -d -d -v -v -v" and compare the two systems, paying particular
attention to differences that involve "aspacem".

Does your QNX have tools such as gdb and strace or dtrace?
It will be helpful to know the address mappings at the time of the SIGSEGV.
