Hi people,

As a newbie, I really appreciate the friendly and helpful D community. Thus, I hope that somebody will be kind enough to help me out with the following problem.

Trying to compile Miguel Simoes' XmlNode.d into a project of my own, I run into the following compiler (or linker) error. Everything goes fine during parsing and semantics, then it starts generating code for the various functions; then, out of the blue:
...
Internal error: ../ztc/elfobj.c 1251

Could someone smarter and/or more knowledgeable than me explain why and, more importantly, how I get rid of it? I'm using Mandrake Linux 10.0 and DMD v. 0.106, if that is any help.

Thanks in advance,
Dimon

One of the standards is to test the newest release - see Walter's URL.

Simones' code requires a little adaption for recent compiler changes:

Thanks, I'll do that. I already changed the little errors you mentioned below (although my solution was not quite as elegant as listed below), so that's not what's causing the internal error. I'm going to upgrade to 0.109 ASAP and see if that does the trick, otherwise I'll post a bug report.

Thanks for the help.
Jan.

Hi again,

just a little follow-up; perhaps somebody might be interested...

0.109 gave the same error. The problem turned out to be a switch statement of the form

switch(stream.readCurrent()) {
	case '>': return true;
	case '/': // do stuff, return false, possibly throw an exception
	default:
}

in a method that returns a bool. I fixed it by doing the following in stead:

bool flag;
switch(stream.readCurrent()) {
	case '>':
		flag = true;
		break;
	case '/':
		// do stuff, set flag, possibly throw an exception
		break;
	default:
		break;
}
return flag;


Does anybody know if this is an error caused by some strange Linux/Win32 discrepancy or something like that?

Cheers,
Jan

Uhm right, but since I could come up with such a simple workaround it wasn't actually a bug ... was it?

OK, I'll shut up now and go look at it in more detail... :-)

Cheers,
Jan

I just ran into it, too, when compiling the Locks library on Linux. I'll try to narrow it down and post something to the bugs newsgroup.
