Subject: [Bug python/11765] New: Pretty printer lookup fails with lambda functions
Date: Tue, 29 Jun 2010 04:12:00 -0000	[thread overview]
Message-ID: <20100629041212.11765.wittman@acm.org> (raw)

When multiple lambda functions are added to the current objfile's pretty
printers, all but one are never invoked.  (It appears that the second-to-last
lambda function added is instead invoked once for each function added.)

To reproduce:

simple.c:
  int main(int argc, char *argv[]) { return 0; }

a.out-gdb.py:
  def test(i):
    print 'test(%d)' % i
    return None

  for i in range(0, 5):
    gdb.current_objfile().pretty_printers.append(lambda val: test(i))

run:
gcc -g simple.c && gdb -ex 'b main' -ex r a.out
