That's the first thing I thought too. Some mismatch between a header and a library, but I've double checked and I can't find anything installed except the Fedora headers. > Is the problem specific to your exact platform? glutSimple runs fine > elsewhere, including the Windows and Ubuntu boxes here. > Somehow it must be. It is the MatrixTransform constructor that is stepping on the mutex data. In debugging I noticed that _refMutex is located at 0x1b45ca8 and points to 0x1b45e20 and _prvData points to 0x1b45e40. Then, when the MatrixTransform constructor is called after all the parent constructors, _matrix is initialized at address 0x1b45d98 and then _inverse is initialized at address 0x1b45e18. Thus _inverse is overlying the memory location _refMutex was allocated at. I thought it might have something to do with the mutable keyword, but I just wrote a small test that dynamically allocated a class with two two-dimensional arrays (like the matrices) and in a parent dynamically allocates another member... and no issues. Which leads me back to thinking that an improper header is the issue. But, I've grepped all of /usr/include for any other header that includes a class named MatrixTransform and osg/MatrixTransform is the only one. I'm going to rebuild inside of a clean chroot and see if anything changes. > -Ben > >> -----Original Message----- >> From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of >> [EMAIL PROTECTED] >> Sent: Tuesday, June 03, 2008 6:40 AM >> To: osg-users@lists.openscenegraph.org >> Cc: [EMAIL PROTECTED] >> Subject: [vtp] Segfault in VTP, but looks like OSG >> >> I'm having trouble with a segfault in VTP's glutsimple application, but >> it >> looks like the problem traces back into OSG.
