FYI I am testing VirtualTreeView with its "Advanced" demo program. When I use FPC 2.5.1 and compile it with -O1, it works always however much I click the different forms. When compile it with -O2 and click and test furiously it finally throws SIGSEGV. The message box says:
Project Advanced raised exception class 'External: SIGSEGV'. Often it paralyzed my KDE desktop partly so that mouse commands didn't work. Then I selected terminal using keyboard and killed gdb and then things worked again. Sometimes it didn't freeze. I tested the same VirtualTreeView code (with my added $packset directives) also with FPC 2.2.4 and it worked with or without optimization. I understand the compiler is a devel version but if you need a good test case, here you have one. I compiled whole Lazarus with FPC 2.5.1 and -O2 and it works well. VirtualTreeView has non-portable assembly code and may be difficult for the compiler.
