Segfault when clicking mouse buttons randomly, etc

[veksha]

started tr1 game, level 0. was all fine. was running around for a long time.
then I started to press mouse buttons randomly (we can see Test_SecondaryMouseDown in a back trace below)
and jumping around at the same time (space/ctrl/shift/x, etc) . so I recieved segfault.

Thread 1 "OpenTomb" received signal
SIGSEGV
source /home/yura/git/OpenTomb/src/room.cpp:384:10187:beg:0x5555556ad474

Line:
int x = (int)(pos[0] - room->transform[12 + 0]) / TR_METERING_SECTORSIZE;
-------------------^^^
error here.
When I jumped up one frame on the call stack (physics_bullet.cpp:84) I noticed
that m_cont->sector was null.
So argument m_cont->sector->pos can have garbage address. am I wrong?
