... both cause GDB to crash with an invalid free. This is because
exec_file_attach is attempting to free a string that has not been
allocated. The string is only allocated if openp is successful.
But in the case of this obviously invalid filename, openp fails,
and leaves scratch_pathname uninitialized, thus causing the xfree
to fail.
The fix is to enable the associated cleanup after we have verified
that openp was successful.
gdb/ChangeLog (By Keith Seitz <keiths@redhat.com>):
* exec.c (exec_file_attach): Move cleanup after verifying that
memory has in fact been allocated.
gdb/testsuite/ChangeLog:
* gdb.base/empty_exe.exp: New testcase.
There are a bunch of aliases that get used with help, but the current
command completion logic does not include those when doing completions.
Since the framework is already mostly in place, extend complete_on_cmdlist
slightly to pass down the ignore_help_classes flag like is done with the
existing lookup command logic.
Now you can do:
(gdb) help use<tab>
and get back:
(gdb) help user-defined

That was an attempt at handling the targets where sizeof(long double)

this testcase verifies to come back without being noticed.
gdb/testsuite/ChangeLog:
* gdb.base/ldbl_e308.exp: Remove "inf" from possible expected
output for "print inp" test.
Assuming the following variable definition:
long double inp = 2.0;
On platforms where "long double" is a double precision IEEE flaoting
point, GDB currently behaves as follow:
(gdb) set variable inp = 1.6e+308l
(gdb) p inp
$2 = inf <<<<---- !!!!
Instead, the value of "inp" should be printed as:
(gdb) p inp
$1 = 1.6e+308
The problem is due to a small error in the comparison of the exponent
versus the maximum value this exponent can take, causing us to think
that the value was too big to fit. But it isn't.
