 I ran a QM (NOT QMMM) simulation on a small molecule, but tried to open the ORCA output in VMD 1.9.4a12 because I know this version of VMD can still open orbitals correctly. At least, I can open the ORACA orbitals from my QMMM simulations. But, with this QM simulation I get a segmentation fault and VMD crashes. I ran the debugger and then typed where. This is the result:

(gdb) where
#0 0x00007ffff05bd207 in raise () from /lib64/
#1 0x00007ffff05be8f8 in abort () from /lib64/
#2 0x00007ffff05ffd27 in __libc_message () from /lib64/
#3 0x00007ffff0608489 in _int_free () from /lib64/
#4 0x00007fff8d469cf5 in close_orca_read(void*) ()
   from /panfs/
#5 0x0000000000839caf in MolFilePlugin::~MolFilePlugin() ()
#6 0x000000000078875c in CoorPluginData::next(Molecule*) ()
#7 0x000000000083013a in Molecule::prepare() ()
#8 0x000000000078e6ec in Displayable::draw_prepare() ()
#9 0x000000000078e716 in Displayable::draw_prepare() ()
#10 0x000000000089d395 in Scene::prepare() ()
#11 0x00000000008c8d71 in VMDApp::VMDupdate(int) ()
#12 0x000000000

I don't know what to make of this. I don't have the background to interpret the cause.
