gdb refuses to connect to localhost

Hello again!

I captured with wireshark the communication. They do seem to communicate 
is just it seems gdbserver is sending this weird stuff that I don't 
know. I guess you guys neither if it does not look familiar:

> >     Sending packet: $qSupported:multiprocess+;swbreak+;hwbreak+;qRelocInsn+;fork-events+;vfork-events+;exec-events+;vContSupported+;QThreadEvents+;no-resumed+;xmlRegisters=i386#6a...Sending packet: $qSupported:multiprocess+;swbreak+;hwbreak+;qRelocInsn+;fork-events+;vfork-events+;exec-events+;vContSupported+;QThreadEvents+;no-resumed+;xmlRegisters=i386#6a...Sending packet: $qSupported:multiprocess+;swbreak+;hwbreak+;qRelocInsn+;fork-events+;vfork-events+;exec-events+;vContSupported+;QThreadEvents+;no-resumed+;xmlRegisters=i386#6a...Sending packet: $qSupported:multiprocess+;swbreak+;hwbreak+;qRelocInsn+;fork-events+;vfork-events+;exec-events+;vContSupported+;QThreadEvents+;no-resumed+;xmlRegisters=i386#6a...Timed out.

I have attached the raw wireshark capture of the communication. I am not 
too versed in networking so I don't see anything out of line other than 
gdbserver sending the above weird stuff.

I have tried multiple things. Just debugging a simple hello world, I 
checked pacman to see if any of the default installed files have been 
altered and they have not, I removed `.gdbinit`. The `gdb` installation 
is the default one from `pacman`:

  https://archlinux.org/packages/extra/x86_64/gdb/
  
Just really strange behavior. I have a desktop and a laptop and I can 
reproduce the same behavior in both. They are both very similar in linux 
setup, packages, etc.

Just really scratching my head here.

Thanks,
Reinaldo Molina
