Swelio 1.9 is available for download: https://github.com/perevoznyk/swelio-sdk
In this release the memory allocation problem is fixed with help from Tim Messiaen. The problem causes errors in 64 bit mode and under debugger. I would recommend to all users to update to this release.
Additionally, the library to sign PDF documents with Belgian id card is available on GitHub: https://github.com/perevoznyk/swelio-pdf
