Prevent PLT (procedure linkage table) breakpoints in GDB

Question

In recent versions of GDB, setting a breakpoint on a library function call results in multiple actual breakpoints:

1. Call into the procedure linkage table (PLT)

Answer 1

add these lines to your ~/.gdbinit file and call disaplts to disable all @plt breakpoints:

define disaplts
  python
import gdb
from StringIO import StringIO
lines=gdb.execute("info break", True, True)
for l in StringIO(lines).readlines():
  if "@plt" in l:
    bp=l.split()[0]
    gdb.execute("disa {0}".format(bp))
    print("disabling {0}".format(bp))
  end
end
# disable on library load
catch load mylibrarywithplt disaplt

Note: mind the spacing in python code. I recommend you use cat to paste the content. EDIT: added "execute on library load" per @WallStProg
