Description
I'm running a Yocto Hardknott with basler meta layer and a Basler A2500-60mci.
Everything is working just fine, i was able to create my application easily.

When I tested it using Valgrind though, I noticed some memory leaks on basler library (total of 616KB),
and I wanted to ask if this could be false positive or something else.

Thank you

Thanks for the valgrind report. We will look into the issue.

@simoberny Could you provide more information on the exact versions you are using? In the valgrind log it is called "basler-daA2500-60mci-imx8.cti". But the producer in this layer is named "basler-daA2500-60mci.cti". You can get more details by executing the cti file as binary (e.g. ./basler-daA2500-60mci-imx8.cti )
