Hi Mohammad,
Lia has looked into this problem and it seems that the
problem originates from -O2 option in the setting
of the environmental variable CMAKE_CXX_FLAGS_DEBUG.
We have gcc 3.4.6.Without this option the routine works correctly.

We have looked into 3.4.6 manual and we found this:
"
Unlike most other C compilers, GCC allows you to use -g with -O. The shortcuts taken by optimized code may occasionally produce surprising results: some variables you declared may not exist at all; flow of control may briefly move where you did not expect it; some statements may not be executed because they compute constant results or their values were already at hand; some statements may execute in different places because they were moved out of loops.
"

In CbmTrackParP there is a call to the routine that changes
track representation that seems to depend on this compilation flag.

Do you have any idea?

Ciao,
Andrea and Lia
