I really hope we don't need to specify all struct fields. What warnings does the compiler give you, exactly? In any case, please let's discuss it on wx-dev. TIA! |

This makes things much, much slower, but unfortunately seems to be the
only way to avoid memory leak reports when running the tests as without
it the suppression is not used because the stack is truncated, i.e. we
only see
Direct leak of 24 byte(s) in 1 object(s) allocated from:
#0 0x7f0968253bc8 in malloc (/lib/x86_64-linux-gnu/libasan.so.5+0x10dbc8)
#1 0x7f09675aacb8 in g_malloc ../../../glib/gmem.c:102
in the output when the actual stack, seen with fast_unwind_on_malloc=0, is

Somehow ASAN reports a memory leak in this test:

but only if another wxDataViewCtrl test runs after it, i.e. there is no
leak when running just this test on its own.
This doesn't seem to make sense, as wxDataViewCtrl, and hence
GtkTreeView, is destroyed at the end of the test and it shouldn't be
possible for a test running later to affect the presence or absence of a
memory leak in it, so it might be a LeakSanitizer bug, but this doesn't
help actually getting rid of it.
The only other possibility would be to suppress this leak, but this
doesn't seem ideal, as we could suppress some other real leak too, so
for now just skip this test when using ASAN.

This seems to result in a false positive in BitmapComboBoxTestCase with
the following stack:

There are a lot of warnings about uninitialized variables when compiling tests with gcc. This patch fixes most of them.
