Forum Topic - too shallow stack frame when using backtrace library under QNX650: (2 Items)
   
too shallow stack frame when using backtrace library under QNX650  
When generating backtraces using backtrace library the stack frame is limited to 3 functions only for QNX650.
It can also be seen when using pidin utility with %q format.
For QNX641 the stack frames were deeper.

Is there way to increase the limit under QNX650?

Re: too shallow stack frame when using backtrace library under QNX650  
The way bactktrace depth is being calculated in pidin has not changed 
between 6.4.1 and 6.5.0.

The success of backtrace depends on the architecture. For example, on 
arm, libbacktrace does not do a good job.

The difference in backtrace depth may be caused by the generated code 
(i.e. different compilers used in 6.4.1 and 6.5.0), as libbacktrace 
tries to decipher generated code which is very tricky.
