Hi all

Currently I am debugging a nasty shared memory bug. More specifically it's related to memory allocator, though not directly.

More to the point - lack of backtraces is really tough - Lazarus debugger just shows one level. Upon some investigation I managed to get much more meaningful backtraces. However the only way to enable them which I found is manually editing root Makefile.fpc and removing all RELEASE directives (giving executing make DEBUG=1 does not help) and compiler rebuild to avoid -O2 optimizations.

So the question is why it's so difficult to build fpc compiler/rtl in debug mode? Is it possible to fix? Or maybe I miss some official way?

You don't need to edit Makefile.fpc. When I need debug info for rtl and packages I use this:

make clean all LINKSMART=1 CREATESMART=1 DEBUG=1 OPTIMIZE=0 OPT="-gl -gw -godwarfsets -O-1"
