Question

I have developed a program which makes use of serial programming to read and write from serial port and put the values in databases in Ubuntu environment. Lately, I have added few functionality using boost lib to filter the read function etc. But when I run the program , say after 15-20 mins , I got segmentation fault .
When I check the log file which I have defined in my program I got following lines in it. I have no clue what is all about. Can someone guide me on that.

Answer 1

Easy answer. Your program segfaulted. That means its is no longer working and it can behave badly.

In this case it started to print out a string (probably not properly terminated) and it was continuing to print out the program memory. And you have probably included the GNU GPL license text which is long. The possibility that segfaulted program will print some of these strings is high.

Check your memory allocations, strings etc. You are facing a memory related bug.
