1/ I have been stuck into debugging process of some code,
Am getting a: 'Floating point exception (core dumped)' which pop up randomly:
In other words, I have tried to find out was that related really to an arithmetic error of division by zero, and I fixed all possibilities of getting the error because of that, however now every possibility of getting division by zero is eliminated I still get the error and worse every time am running the code I get the exception raised from a different place.
Reading more on that exception on GR forum, I did not understood how could connecting a packet modulator with a USRP sink, raise such exceptions,
(the context is as follows: a "mod_pkts_sptr" connected to "usrp_sink"
Inside the section of "mod_pkts_sptr" there is a thread generating packets and sending them continuously)
Please, if there is any hints or explanations I will be very pleased,
2/ Apart from that is there any accurate way to ask gdb to locate exactly which instruction is erroneous or which section of the code is causing trouble.
3/ Is that a correct way to connect foo block to a currently described block:
