Internal error 200312122

Koenraad Lelong-2
When I try to compile the MSEgui demo for arm (using fpc 2.0.2, MSEgui
0.7) I'm getting that error when compiling msegui.pas. Where should I
look to solve this ?
I tried some shuffling in the uses-header (I found this in this list
when I searched for internal errors), but this didn't work.
I can provide more info (output of MSEgui, fpcdebug-file).
B.T.W. I made a spec file to make an rpm for fpc 2.0.2. Anyone
interested ? Of course you need a toolchain for arm.
Regards,
Koenraad Lelong.

Try to rebuild all units.
use the -Ba compiler option

I think I had this same issue when I tried MSEgui long ago, and it only occurred if I
did not request -Ba option.

Just tried it, doesn't work :-(. Compiling with ppc386 for i386-linux
works fine, compiling with ppcrossarm for arm-linux gives the error.
Could this be a processor specific error ?
Thanks anyway,
Koenraad Lelong.

compiler/cgobj.pas:548:

    function tcg.getintregister(list:Taasmoutput;size:Tcgsize):Tregister;
      begin
        if not assigned(rg[R_INTREGISTER]) then
          internalerror(200312122);
        result:=rg[R_INTREGISTER].getregister(list,cgsize2subreg(size));
      end;

OK, now I know that I can search for such an error. I assumed they were
put together in the source (somestring1+somestring2...).
I'm going to look at that (although with little hope, I'm not into
compilers ;-)).
Thanks,
Koenraad Lelong.

Internalerror numbers are just unique numbers be using <date><seqnr>. They
don't have any meaning.

Quick intro for debugging this.
- Build compiler with debug info: 'make cycle OPT=-gl'
- Compile source with this new compiler in gdb:
   - gdb --args <newcompiler> <args>
   - (gdb) br INTERNALERROR
   - (gdb) dir <pathtocompilersource>
   - (gdb) r
   - Hit breakpoint
   - (gdb) bt
   - The backtrace will give you more info. Use 'fr <framenr>' to jump to
a function in the callstack so you can watch the code and variables.

OK, I tried this, but that's as far as I can get. Enclosed the output of
the backtrace (first lines are the commandline I used).
Anything I can do further ?
Thanks,
