Hi, I am new in the community.

I am trying to use gdb in MacOS Catalina 10.15.7 with gdbgui and I obtain the
following warning message:

BFD: /usr/lib/dyld(i386:x86-64): unknown load command 0x34

I think my problem is similar. I can work more or less with gdb, but I note a
deficient performance of some tools.

Hey Remi. Did you ever find a fix to this? 

I am on macOS Ventura. I am running a simple c++ "Hello World" program. I
cannot get gdb to work properly. 

Basically, when I run gdb on the application, it will hang. When I press
ctrl-c, the program continues, prints out what was intended and then shows me
an error.

```

Just FWIW, right now nobody actively maintains the macOS port.
Basically gdb needs a knowledgeable volunteer to help keep it up to date.

Hi Corey, I think I switched to lldb at the time.

I would gladly try to fix this but have honestly no idea where to start.

The problem I am having currently is that I do not thing lldb supports fortran.
I am looking for another way to debug .f90 files. 

Do you know of any other options?
