[MiNT] This must be an gcc / ld error!

["Ole Loots" <ole@monochrom.net>]

Sorry, I'm still messing around with gcc,..., I can't stop now.

I'm trying to port a project, without your help I would have not finished
the compilation / linking phase. Thanks for that! :)

After everything had been linked, I thought I could try to start the
Program, of course I was prepared for anything (or nothing at all)!

Well, it did not work, the executable returned error code 1.

So I got in contact with the developers of netsurf - someone there told
me: "running libnsfb 'make test' is your first step in porting netsurf".
(libnsfb is a framebuffer library with support for sdl
framebuffers/surfaces).

OK, I did that. The make file produced some test executables... any of the
produced executables throws an Illegal Instruction exception. I removed
the -O2 flag from the compiler options and I also removed the -g option.

Both results in the same Invalid Instructions.

I tried to load the test cases with gdb ( also with gdb-7.0 provided by
Vincent ) but when I do:

b main

I get an Bus error (just if I compiled with -g ! - else i hit the Illegal
Instruction). So I expect the executable is not build like it should have
been build. GCC produced "garbage" ;) Of course it did not produce garbage
- but maybe it sets the entry point to something wrong, or such thing?

Btw. I don't want to bash on gcc etc. - I'm just working with it ;)
It's good to have an new gcc version for the Atari, of course ! :)

Here is the gcc commandline that produces the bad executable:

Maybe someone is willing to comment on this...?
