[PATCH 0/3] Fixed abortion using Python API for label symbol object.

[Maxim Bublis <satori@yandex-team.ru>]

Hi,

There is a problem with calling .value() method for label symbol object,
i.e. symbol object with it's .addr_class == gdb.SYMBOL_LOC_LABEL.

If you debugging code similar to that:

int main() {
	abort();

some_label:
	return 0;
}


and if you are running something like that (frame with `main' function should be selected in this case):

gdb> python "print list(gdb.selected_frame().block())[0].value(gdb.selected_frame())"

gdb will fail with SIGABRT.

Following patchset adds testcase, fixes problem and documents this behavior.

Maxim Bublis (3):
  gdb/testsuite/gdb.python: Added testcase for .value() method
  gdb/python: raise TypeError instead of abort() on calling .value()
    method for label symbol object
  gdb/doc/python.texi: documented gdb.SYMBOL_LOC_LABEL. Added notion on
    possible exception thrown from symbol object .value() method
