Hi folks,

can someone with access to Ubuntu _12.04_ please have a look at this
POV-Ray branch (a pending pull request), see if the binaries crap out on
their machine as well (complaining about "pure virtual method called"
and some stuff about pthread, boost and mutex), and if so, figure out why:

https://github.com/eblanca/povray

Your help would be much appreciated.

Sorry to disappoint you, but it's working, at least with -D option:
* ubuntu 12.04.5 LTS
* g++ 4.6(.3)
* 64 bits system (x86_64)



-D is due to my local setting (X11 remote display is not setup to allow 
this machine to display on my screen)

With +D (or default), I got a core dumped. (but it seems unrelated to 
that branch and might be a problem for all branches)

With DISPLAY not defined, it's strange: there is an ascii preview, then 
statistic and the telnet/shell is frozen. (yet, probably still the same 
for all branches)

unix/povray --benchmark : ok
unix/povray with small scene (3.7, 1 sphere) : ok

No access to Ubuntu 12.04, but it does run just fine on Debian/testing and
FreeBSD.

That's of little help to me. I already know that this thing runs fine on
/some/ systems.

I need someone to get this baby to cry in a controlled environment, to
figure out why it does so in our Travis CI automated build test
environemnt, and ideally find a way to soothe it there.

It might just be afraid of the dark (read: having no terminal
associated, or some such), but at the moment that's just a wild guess.

Someone else said it works fine on their Ubuntu 12.04 system. Perhaps it's
specific your particular hardware configuration?

pure virtual called is usually a problem of code vs compiler vs linker.
(child class declared the method, but did not implement it)

It can also be a problem of a fool pointer being interpreted as a 
pointer to a class that is not the expected one anymore. (such as to a 
deleted instance) and then, it can depend a lot on the actual system 
usage about what is found in the memory for that pointer. Memory 
problems can be due to race or serialization between cores.

I tried it on 64 bits ubuntu 12.04, with g++ 4.6.3, and 4 cores.

It could also be tied to the subversion of g++ (I cannot update that 
system, and maybe 12.04 did not stay at 4.6.3), or 32 vs 64.
