SIGSEGV error on closing program with ActiveXContainer lazarus / 5-Lazarus Extra Components ---------------------------------------------------------------------- flaza ยท 2019-02-07 10:59 Hi, I'm using Lazarus 1.8.4 32bits on Windows10. I'm trying to use ActicveXContainer to show helpfiles in my program. That works fine. But I get the SIGSEGV error when I close the program while running it in the IDE. The worst part is: the de OnDestroy procedure from the main Form is not executed. And I need that to free some objects I use. I can't figure out what I'm doing wrong. I used the code on the wiki page http://wiki.freepascal.org/LazActiveX. I've attached a small example program to show you what I have done. Hopefully, someone can help me. Frans
