I don't think they're related. The bunches of errors occur because
gdb-info-breakpoints-custom only parses the output of "info breakpoints"
properly when they are at a statement boundary (have a line no. associated
with them) to place to breakpoint icons. There will be similar problems with
"info frames".

I don't know exactly what happens if gdba starts without "--annotate=2" but
the annotations are needed to tell it the status of the prgram. "--fullname"
just gives line information for display of the source. 

Looking at it, gdba doesn't freeze but to seems expect its input to come from
the input/output buffer (try, for example, typing break main in there)

You could infer how gdb was running from the lack/type of annotations (=1, =2)
but I don't think this would be easy. At the moment I run two gdb commands
requiring annotations *before* the executable is run to find out in what
file main is stored.

I've also used insert-buffer. C-h f gives :

  This function is meant for the user to run interactively.
  Don't call it from programs!

What should I use this time ?
