This output of truss is typed in, so be gentle with my mistakes:
/1; fpathconf(6, _PC_NAME_MAX) = 8
/1: lstat64("/rmdisk/unnamed_rmdisk/wd_windows_tools/EULA/ENG/MemeoAutoSynclicense.pdf", 0xFFBFCFC8) = 0
/1: Incurred fault #5, FLTACCESS %pc = 0xFDDD49B4
/1: siginfo: SIGBUS BUS_ADRALN addr=0x666D9676
/1: Received signal #10, SIGBUS [caught]
/1: setcontext(0xFFBFC938)
/1: Incurred fault #5, FLTACCESS %pc = 0xFDDD49B4
/1: siginfo: SIGBUS BUS_ADRALN addr=0x666D9676
/1: Received signal #10, SIGBUS [default]
and there it is dead.
If I do this file on its own, there are no problems.
However I can also get it to do this (if I run over the same directory structure, but at a higher starting point)
/1; fpathconf(6, _PC_NAME_MAX) = 8
/1: lstat64("/rmdisk/unnamed_rmdisk/wd_windows_tools/EULA/ENG/MemeoAutoSynclicense.pdf", 0xFFBFD2F8) = 0
/1: Incurred fault #6, FLTBOUNDS %pc = 0xFDDD4D58
/1: siginfo: SIGSEGV SEGV_MAPERR addr=0x0000001C
/1: Received signal #11, SIGSEGV [caught]
/1: siginfo: SIGSEGV SEGV_MAPERR addr=0x0000001C
/1: setcontext (0xFFBFCC08)
/1: Incurred fault #6, FLTBOUNDS %pc = 0xFDDD4D58
/1: siginfo: SIGSEGV SEGV_MAPERR addr=0x0000001C
/1: Received signal #11, SIGSEGV [caught]
/1: siginfo: SIGSEGV SEGV_MAPERR addr=0x0000001C
which is also quite fatal.
