Using TFS 1.3

I have made some modifications in the sources and am facing segmentation fault 11 crash.
I tried debugging with lldb ( it wasn't compiled with -g flag )
Code:
(lldb) target create tfs
Current executable set to 'tfs' (x86_64).
(lldb) run

...
... TFS log here
...

Process 27477 stopped

This didn't seem clear enough and I went on to compile with -g flag but even then there was no human-readable debug info.
All I get is lowlevel info.


I have also tried with GDB, but no luck with that one either
Code:
warning: `/tmp/lto.o': can't open to read symbols: No such file or directory.
warning: `/tmp/lto.o': can't open to read symbols: No such file or directory.
(No debugging symbols found in ./tfs)



I added the -g flag here, in CMakeLists.txt:
Code:
if (NOT WIN32)
    add_compile_options(-Wall -Werror -pipe -fvisibility=hidden -g)
endif ()

What should I try next?



EDIT (02:09 AM):
Did some research, came across this post:

Compiled with -g -O0, executed image lookup -vn <theCPPFunctionNameHere>
and the output has no CompileUnit and according to the answer on the SO-post:
If the output of that command includes a CompileUnit, then the .o file containing that function has debug information, otherwise, not.

pepothink.pnghmm, what to do?

What do you mean?

I've mentioned that I tried gdb :confused:
warning: `/tmp/lto.o': can't open to read symbols: No such file or directory.
