on gdb, LoadLibrary mets sti instruciton and singals SIGILL
In my program I load a dll during runtime with LoadLibrary. Every thing
works ok when running in release mode.
But when I try to run program in debug mode, the load library stops with
SIGILL, debugger shows it stops on sti instruction.
I also tried to link dll during program load by direct call from dll. But
I get SIGILL during program load.
I am using mingw48 shipped wit qt5. I am not interested in debugging that
dll, only to debug the other, self written part of code.
I as I found so far sti/cli instructions are only in privileged code. As I
understand code running in gdb is not privileged.
I have already tried to ignore signal with ::signal(SIGILL, SIG_IGN); and
gdb command handle SIGILL pass nostop noprint with no effect.
What I realy need is to load that library in some non debug mode while the
rest of program is being debugged.
