Do you think it might be bug 1439? (note that the test case probably
doesn't work any more, since Walter started hashing ultra-long mangled
names, but the point remains that there's a (narrow) range of symbol
lengths which will kill OPTLINK). Or yet another instance of bug 424? Or
is likely to be something else? (IE, is your code template-heavy?)
I can't make bug 2817 crash, and it's the only other plausible optlink
segfault in bugzilla.
I don't think it's 1439. The crash actually only shows up when I use -g
or -gc when I'm compiling. If I leave that off, it's fine.
It's when I try to use tango.math.random.Random that it starts crashing.
I can use one method from that module, it's fine. If I try to use more
than one, it blows up. Note that it's quantity, not a specific symbol.
Plus, if I compile the module with just a dummy main method, it's fine.
It MIGHT be 424. I'm getting the crash at EIP=004244FB. I'm not
getting a fixups error message, if that's part of the symptoms, though.
My code isn't "template-heavy" (at least, not by my standards), but the
Random module does appear to be.
I'm toying with a little OMF dumper program at the moment. I suppose
that's the easiest way to see if I'm hitting the fixup limit...
You could try objconv from www.agner.org. Might work.
Incidentally, if Walter or yourself would like the object files causing
the crash, I can provide those (probably via private email). I just
can't upload it generally since it's a private project.
