Cloud cloud library application applications are difficult to debug, possibly due to streaming?

Question

I use the Point Cloud Library with cmake to compile, and I have it in debug mode, but my program did not cancel the error or did not interrupt as I expected.

In particular, I get these messages:

(gdb) run bunny
Starting program: debug/our_cvfh bunny
libc++abi.dylib: terminating
[New Thread 0x170b of process 80178]

Program received signal SIGABRT, Aborted.
0x00007fff88c6f866 in ?? ()
(gdb) bt
#0  0x00007fff88c6f866 in ?? ()
#1  0x00007fff8bb5235c in ?? ()
#2  0x0000000000000000 in ?? ()
(gdb) break rec/registered_views_source.h:305
Cannot access memory at address 0x961d60

In this case, I know where the error is, but I would like to be able to return output and see what is called a function in this case.

Does the PCL create another thread, and why can't I backtrack? I am not doing any visualizations right now, so I cannot understand why it will use streams.

I also tried to run the program in the debug directory, and not in the root directory of the source code. Here's another example of this not working:
