2014.0.0 assert errors in hugin and PTBatcherGUI

[Andreas Metzler]

Hello,

on Debian some of our users still see assertion errors with hugin 2014.0.0 (plus 52_044b08eb6adf_Several_fixes_to_treelistctrl.diff and 53_f88dc95914ae_Use_correct_class_wxStaticBitmap_for_bitmap_controls.diff) either in hugin itself or in PTBatcherGUI:

I'm starting with:

$ hugin IMG_4749.png

open: View -> Panorama Editor

in Panorama Editor:

Select tab: Stitcher
switching to format png (but shouldn't matter)

and click the "Stitch!" botton which triggers (sorry forgot to add this too):

Click: Continue

In the "Save project file" Window

Click: Save

Which triggers:

Something seems to be broken in either hugin or wxgtk3 right now.

Starting hugin with no existing configuration gives me the following startup
assertion failures:

$ hugin

When trying to stich a panorama, the following assertions are emitted:

I was thinking that something was broken in libwxgtk3, but I'm also using pgadmin3
and it seems to work just fine.
-------------------------------

Both submitters see these as the messy click-and-confirm assertions. Personally I see the assertions Yuri reports on the starting console, without click-through

Changeset 59938e35626e2a5efb681597047414921bbc5e4d should fix the assert error with wxArgNormalizer in FillPlaceholders and ProjectListBox::GetAttributeString

But I can't reproduce the issue with
.../include/wx/datetime.h(1740): assert "IsValid()" failed in GetTicks(): invalid wxDateTime
.../src/common/datetime.cpp(1392): assert "IsValid()" failed in GetTm(): invalid wxDateTime
Here I need more information (maybe a longer backtrace?)
TIA

Hi Andreas,

just one question: I don't understand why the assert triggers a message at all.

From the documentation (http://docs.wxwidgets.org/stable/group__group__funcmacro__debug.html#ga204cc264ee560b67e6c6467ba8ffee5f )

cite: "Please note that the condition in wxASSERT() should have no side effects because it will not be executed in release mode at all."

So this would mean, that Hugin and/or wxWidgets is build as debug version. This would result in speed penalties and for distributing Hugin should be build as release version (not as debug version).

If Hugin and/or wxWidgets are build as release version and the assert still triggers a message box, this should be investigated and maybe report upstreams to wxWidgets.

I've got the very same issue just after upgrading from Ubuntu 14.04 to 14.10 and using Hugin 2014.0.0.5da69bc383dd (from stable
hugin-builds ppa)

[Georg Lipps (georg-lipps)]

I also got these assertion messages:

/usr/include/wx-3.0/wx/strvararg.h(451): assert "(argtype & (wxFormatStringSpecifier<T>::value)) == argtype" failed in wxArgNormalizer(): format specifier doesn't match argument type

messages can be quit with continue

setup is Ubunto 14.04.2 with Hugin 2014.0.0.5da69bc383dd (installed from Hugin PPA Packagers <email address hidden>)

Error was not present with previous version.
