suppressing errors from dmcli

I'm using dmcli on Linux.  It works fine, but every time I call dmcli, after it's done with my command, I get an Error in free(): invalid pointer.

This would be fine except that I cannot suppress that error.  Even if I route stderr and stdout to /dev/null, the backtrace and memory map still print pages of data to the console.

Is there some other way to suppress the error?

I'm using Serena Dimensions CM CLI Client 14.3.3 Build 9.349 (u) on SUSE 12.5
