smt averaged spectrum don't free memory

[magru]

Hi,

I'm developing a cvi 8.0 dll with smt 2.1 (NI spectral measurement toolkit), called from a VC++ task.

after a long time of utilization my task have windows error "not enough memory".

analizing memory occupation of task in run-time, i see that the "smtaveragedpowerspectrum" function use new memory when called with parameter restart = 1 and don't free the memory allocated before (also when i destroy the smt handle the memory don't decrease).

it's a know bug? it's possible to resolve it?

Hi magru,

Are you still encountering this memory leak? If so, I would like to reproduce it on my end so can you provide me with small example that I can look at?

Hi magru,

Thanks for letting me know the bug ID as that helps alot. I looked at the status of the bug ID and it looks like we are currently working on that issue.  Just remember to keep that ID so you can continually check the status.

Thanks.

On NI site there is a new version of SMT (2.3),

you know if the SMT 2.3 solve the problem?

In bugfixes i found nothing about this.

Hi Marco,

No, version 2.3 doesn't have a fix in it.
