Crash after destroying a text overlay in 1.6.2

Postby jfaust » Fri May 22, 2009 10:06 pm

I'm trying to upgrade to 1.6.2 from 1.4.9, and have run into a very strange problem. During first frame rendered after anything using a Font is destroyed, the application will crash horribly:

Code: Select all
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0xb70f3920 (LWP 11375)]
0xb7ab7903 in ?? ()

(gdb)


I tracked the site of the crash down to line 2771 of OgreGLRenderSystem.cpp:
Code: Select all
glDrawElements(primType, op.indexData->indexCount, indexType, pBufferData);


The crash happens if you step over that line, on the first call to glDrawElements after the text is destroyed.

I found a "workaround", which is that if I prevent (comment out) the text element from deleting its vertex buffer, everything seems to work fine... that's not a real option though, as it will continuously leak video (and main) memory.

This is all under Ubuntu 8.04, with what appears to be the latest nvidia-glx-new drivers. I've attached a minimal sample which demonstrates the behavior, it can be compiled with:
Code: Select all
g++ -o font_crash -g font_crash.cpp `pkg-config --cflags OGRE` `pkg-config --libs OGRE`

Alright, I just tested against 1.6.0 and 1.6.1 and it works fine, so this is something new in 1.6.2

Yeah I've been having the same problems with ~Overlay().
Again, my solution has been to stop freeing memory - disaster.

I have had so many other problems compiling and running under Ubuntu 8.04 that I've given up the platform altogether (much less hassle than ripping the entire project apart).

It would be nice if the overlay issue was solved; otherwise I guess the sensible thing is to stick with the old version of Ogre

Re: Crash after destroying a text overlay in 1.6.2

Postby AntonTheManton » Thu Jul 02, 2009 10:03 am

Okay - found the problem. (I'm on Ubuntu Jaunty)
OGRE is not compiling against g++-4.3. Definitely a problem with OGRE's code not being up to the 4.3 spec (and RakNet incidentally).
Solution was to roll back to g++-4.2 and to recompile everything (biggest hitch was that to get OGRE to compile without weird errors I also had to recompile OIS with g++-4.2 - man, that was hard to figure out).
I've only tried the previous release of OGRE (1.6.1) but it's working now.
I can confirm that it is NOT a problem with the new nvidia glx driver.
I assume that the dodgy bit of code is in the Overlay::~Overlay() memory handling.

That doesn't explain our original problem -- we're on Hardy, which uses gcc 4.2, and 1.6.1 works fine for us.

It's also not an issue with overlays specifically, but with everything that renders with a font. The MovableText example from the wiki exhibits the same behavior, and does not if it's using a different material (than the one from OgreFont::getMaterial()).

Don't know if this is related, but i'm getting an Ogre Memory Exception when i destroy Ogre root, only if i use overlays at some point.
I'm using the latest SVN Trunk.
