GQRX received signal SIGSEGV, Segmentation fault.

[bahari]

Hi,
I'm in the process to debug and develop an application based on gqrx source file as a benchmark using qt5 development ide.

I'm already success compile all the dependencies required for gqrx. I'm also successfully compile gqrx application using qt5 ide without any error.

But the problem is when I run gqrx in the debug mode, the system throw segmentation fault with the message: Program received signal SIGSEGV, Segmentation fault.

Below are my GDB traces:

What is really the cause of this problem? For your information I'm using gnuradio version 3.7.10 and I'm compile it from source. For gr-osmosdr I'm using the latest pull from github and I'm also compile it from source.

I think you use some Not-8bit-Charset and there is anywhere a problem with this in the stacktrace.
Not really related to gqrx, I think.
If you have a Non-ASCII letter in your install path, try to change this and retry.
Or update your system and libraries.

I don't see Gqrx anywhere in the stack trace, so it looks like the issue is somewhere else. I'll close this off for now, but if you find that it is due to a bug in Gqrx please let me know.
