[tde-devels] [OT] iscan compiled on debian10 works and compiled on debian11 does not work

Hi, perhaps someone has an idea where I can look into to solve this. I am building iscan packages when upgrading, because I patched the source to support later PNG and with some other fixes. Unfortunately after last upgrade I noticed that the newly build version does not work, however the version build on buster last year still does work. It is the same code and same build process. I don't know where to start looking. I ran through strace and there are few differences around threads and mmap, but as I am not so experienced, I can not decide if this is relevant. Do you have any advice? thanks BR -- FCD6 3719 0FFB F1BF 38EA 4727 5348 5F1F DCFE BCB0
