[M3devel] crashes everywhere (only m3gdb remains unsolved)

[Dragiša Durić]

Another program, similar code... bt before I do set lang (still no idea
why' problem there):

#15 0x00d126f2 in _m3_fault (arg=Invalid C/C++ type code 39 in symbol
table.
) from /usr/local/cm3/pkg/m3core/LINUXLIBC6/libm3core.so.5
#16 0x00d0ef32 in CheckStoreTraced (ref=Invalid C/C++ type code 41 in
symbol table.
) at RTCollector.m3:2316
#17 0x0016bb96 in CreateFont (d=Invalid C/C++ type code 26 in symbol
table.
) at Panda.m3:353

Line 353 is:

    AddDictItem(d, fo.obj, panda.TextValue, "Type", "Font");
    AddDictItem(d, fo.obj, panda.TextValue, "Subtype", "TrueType");
    fontident := "F" & Fmt.Pad(Fmt.Int(d.pdf.nextFontNumber), 8, '0');
  > INC(d.pdf.nextFontNumber);
    (* AddDictItem(d, fo.obj, panda.TextValue, "Name", fontident);
    *)
    AddDictItem(d, fo.obj, panda.TextValue, "BaseFont", fo.f.name());

d is traced, d.pdf is NOT, ie NOT really... a bug was, I've not declared
it "UNTRACED REF", and it is ref to C structure...

I see these RTCollector bugs are happening from time to time, so I am
posting this because I hope it can help other people identify it before
they hit list (as I did:).

m3gdb nastyness remains...
