Well, that is the correct answer. Smilie To elaborate a bit, the code you show is going to overwrite 10 bytes of something else nearby to "destination". Previously you must have had something expendable in those 10 bytes. But you made some changes and now something critical is being placed nearby. Most compilers have options to display the assembler code being generated. Obtain the assembler code for both versions and figure out what was being overlaid in both versions if you really feel the need to know.

NAME
hwloc-assembler-remote - Assemble multiple remote host topologies SYNOPSIS
hwloc-assembler-remote [options] output.xml host1 host2 ... OPTIONS
--ssh <ssh> Use the given ssh command (and options) to connect to remote hosts. --lstopo-path <path> Use the given path as the remote lstopo command when gathering remote topologies. By default, lstopo is taken from the PATH envi- ronment variable. --lstopo-opts <opts> Pass the given lstopo options when gathering remote topologies. --show Display the resulting topology before exit. -v --verbose Verbose messages. DESCRIPTION
hwloc-assembler-remote is a frontend to hwloc-assembler. It takes care of retrieving the remote nodes' topologies before assembling them with hwloc-assembler. EXAMPLES
To assemble three nodes topologies: $ hwloc-assembler-remote output.xml host1 host2 host3 To assemble the topology of a multi-process MPI job defined as a machinefile: $ hwloc-assembler-remote output.xml `cat machinefile | sort | uniq` RETURN VALUE
Upon successful execution, hwloc-assembler-remote returns 0. hwloc-assembler-remote will return nonzero if any kind of error occurs, such as (but not limited to) failure to parse the command line. SEE ALSO
