Segfault Ubuntu 9.04

[Yuv]

Hi all,

I just tried to build the latest SVN on Ubuntu 9.04. The build
completes (though with plenty of warnings about deprecated headers
that I do not recall seeing before) and when I run Hugin it segfaults
(see below). Any idea what I am doing wrong?

This is a (recent) segfault on startup bug reported by several
people here:

http://groups.google.com/group/hugin-ptx/msg/0ae8cc3d73960a4b
https://sourceforge.net/tracker/?func=detail&atid=550441&aid=2793279&group_id=77506

..and possibly this one too:

http://groups.google.com/group/hugin-ptx/msg/9fee1b36f6800713

I can't reproduce this, but it is effectively blocking a release.

some more information.

the previous report was from my notebook (32bit Ubuntu 9.04) for SVN3860.

I now built the same SVN3860 on my desktop (64bit Ubuntu 9.04) and
everything works fine.

I was lucky to have a working Hugin on the notebook for
<http://river-valley.tv/vedutismo-nuovo-new-tools-for-panoramic-perspective-control/>

Unfortunately I don't recall if it was built before or after the upgrade
to 9.04. When I get back to that same SVN number now, it segfaults.

My conclusion out of this observation is that something has changed in
the system / libraries - not in Hugin's codebase. But what is it and how
do we deal with this?

Another thing that I noticed, on both systems, there are many many more
warnings than a few weeks ago. Maybe somebody can make sense out of them:

My idea is that it can be caused by some change in graphics drivers.
What graphics card do you use and which drivers? Maybe we will find
that it's caused by the specific driver.

The Boost library installed in your system uses the deprecated
SGI hash_set container when it should use the TR1 unordered_set
container. A bug report has been filed:

Install the LAPACK development package (liblapack-dev in
Debian/Ubuntu) and edit the includes and Makefile to define
HAVE_LAPACK and the library paths. Or ignore if you don't want
to add another external library dependency.

Probably PrintError() should take a const char* parameter instead
of a char *. I can't find it from the Doxygen documentation,
where is it declared/defined?

(repeated similar warnings omitted)

Missing error checks. Should be fixed to improve robustness of
the code.

Add "#undef DEBUG_HEADER" before the redefinition.

Another case of passing a literal string (const char *) when a
non-const char pointer is expected.

I get the same warning on both machines. The notebook has Intel chipset
(GMA950) and the desktop has nVidia chipset (6150).

thanks. a lot of very valuable input to work on.

This suggests it is either a 32/64bit problem or a difference in
OpenGL capabilities between the two machines. The current trunk is
ok for me on i386.

First you need to exclude one of the many recent OpenGL related
hugin changes. If you roll-back a couple of months (e.g to 3705)
does it still segfault?

These warnings should be dealt with, but they are all problems that
have existed for a long time.

no. it built and started perfectly on the notebook where current trunk
segfaults.

I guess next step is to try and build multiple version in between 3705
and now until I find the commit that is segfaulting.

Got to run now, will take the notebook with me and try that sometimes later.

3838 works, 3839 segfaults

I know Guido says he needs to fix this code, but since you have the
hardware that fails, it would be very useful if you can figure-out
which bit of this commit causes the segfault.

I started to look into that commit and there is quite a bunch of "bits".
The bad news is that I'm unlikely to have time in the coming week. The
good news is that I intend to take that laptop with me on our four weeks
holiday. I'll have a look as soon as I can.

good news

rainy day. I had a little time to test the latest trunk. SVN3899 no
longer segfaults
