New description:

 When I run `lighter2` on armv7 architecture it ends with a bus error; the
 backtrace from gdb is the following:

 {{{
 #0  ComputeObjectGroupLightingT (progressFactor=1, totalPrimitives=597544,
     progress=0x7d834, pass=0, enablePhotonMapper=false,
 enableRaytracer=true,
     objectsBatch=0x4412c740, this=0x4508e1f0, Wait=<optimized out>)
     at /home/ladiun/CS_LATEST/apps/tools/lighter2/scene.h:106
 #1  ComputeObjectGroupLighting (this=0x4508e1f0, progressFactor=1,
     totalPrimitives=597544, progress=0x7d834, pass=0,
     enablePhotonMapper=false, enableRaytracer=true,
 objectsBatch=0x4412c740)
     at /home/ladiun/CS_LATEST/apps/tools/lighter2/scene.h:106
 #2  ComputeObjectGroupLighting (progressFactor=1, totalPrimitives=597544,
     progress=0x7d834, pass=0, enablePhotonMapper=false,
 enableRaytracer=true,
     objectsBatch=0x4412c740, this=0x4508e1f0)
     at /home/ladiun/CS_LATEST/apps/tools/lighter2/scene.h:106
 #3  lighter::SectorGroup::ComputeLighting (this=0x44bd5cd0,
     enableRaytracer=<optimized out>, enablePhotonMapper=<optimized out>,
     progress=...) at
 /home/ladiun/CS_LATEST/apps/tools/lighter2/scene.cpp:630
 }}}

 etc...

 The kernel says:

 {{{
 [102445.635105] Alignment trap: lighter2-2.1 (29772) PC=0x0004ab70
 Instr=0xed808a00 Address=0x44de7a87 FSR 0x811

 [102445.639411] Alignment trap: not handling instruction ed808a00 at
 [<0004ab70>]

 [102445.646757] Unhandled fault: alignment exception (0x811) at 0x44de7a87
 }}}

 I can do some more testing if you tell me what to do...
