Core dump running gqrx built from source

[Cryptik]

I have an Ubuntu 16.04 system that has gnu-radio built from the latest sources using the build-script from Marcus.  The system includes a working install of Qt5 as well as the gnu-radio pre-reqs for gqrx.  I am using a N210 along with the latest UHD drivers (03.10.02), also built from source using the above script.  I have tested that Qt, gnu-radio, and uhd all work using the N210.

I then downloaded the source for gqrx from git and followed the instructions for a command line build using make. It builds with no errors and installs with no problems when using "sudo make install" and then "sudo ldconfig".  When I then run "gqrx -r" it comes up with the config dialog.  I can see an choose the N210 from the dropdown but then when clicking OK, it aborts and indicates a core dump.

The following is shown in the terminal window followed by a memory map.  I am not sure what to make of it or why I can't get it to run.  Hey help would be appreciated.

linux; GNU C++ version 5.4.0 20160609; Boost_105800; UHD_003.010.002.000-0-gbd6e21dc

Have you tried using the N210 in gnuradio through the gr-osmosdr block?

I haven't yet tried gqrx with gnuradio 3.7.11 so there could be some
incompatibilities there. I have no idea.
