I made a simple flow graph using OFDM Carrier Allocator. Please see the attachment. If the attachment is not available, screenshot of it can be found at http://imgur.com/v7aPL7J (Almost same as http://gnuradio.org/doc/doxygen-3.7/page_ofdm.html#ofdm_tx)
When I run the flow graph, it immediately stops running. To debug, I look into `dmesg`, and it shows: *[12785.433257] traps: ofdm_carrier_al[23633] trap divide error ip:7fe08fb3f375 sp:7fe073ffe610 error:0 in libgnuradio-digital-3.7.10git.* *so.0.0.0[7fe08faa2000+f4000]* It's somewhat frustrating because I didn't modify the OFDM Carrier Allocator block. Could anyone suggest a starting point to debug it? OS is Ubuntu 14.04, kernel 3.13.0-96, 64-bit GNU Radio version is v3.7.9.2 If more information is required, please let me know it. Regards, Jeon.
