Dear friends, TDE looks really amazing. Just a quick and a tricky question, I am afraid. Lazarus IDE [1] is a powerful tool for developing Object Pascal applications. It has a strong and enthusiastic community and it gains a lot of popularity lately.  Practically it supports any OS, cpu architecture and graphical toolkit you can think of. Unfortunately, every time I am trying to debug an application in TDE, I keep getting the following message and crash  /"Project raised exception class 'External: SIGSEGV'.// // // In file '../sysdeps/x86_64/multiarch/../strlen.S' at line 120// // //The file "/build/glibc-OTsEL5/glibc-2.27/sysdeps/x86_64/strlen.S" was not found.// //Do you want to locate it yourself?"/ When I am trying to execute my precompiled//application I get the /" The application gtk2-tqt-engine (BigProject-gtk-tqt-application) crashed and caused the signl 11 (SIGSEV). "/ As I said in any other OS (Windows) and in many different linux distros (Mint, MX)  with different Window Managers (Mate, Xfce, etc) it runs without a hitch. Any ideas? I am trying with latest TDE R14.0.7 / Mint 19.3 Best Regards, Vasileios Vlachos [1] Lazarus IDE: https://www.lazarus-ide.org/
