I don't think that's an OPTLINK bug -- that obj file seems to be defective. And it's a really complicated obj file! Provide the source code for the smallest case which reproduces the problem.
Is it the same as #1439?

Then I think it's both dmd and optlink bug. The former is buggy because it produces invalid object file. The latter cannot gracefully recover from invalid input, so it's buggy as well. >And it's a really complicated obj file!

But it probably won't get fixed unless you can simplify it. Mind you, OPTLINK is unlikely to get fixed, anyway. But maybe Walter can change DMD slightly to work around the optlink bug. >> Is it the same as #1439? #1439 shows that something bad happens when the symbol length is a particular length (out-by-1 error?). I think this is quite likely to be the same issue, since you have so many templates in there. |

I think this is quite likely to be the same issue, since you have so many templates in there. It may be that issue. But it seems to depend not only on the length of a particular symbol generated by a template instantiation. For example, the error dissapears when I remove an unreferenced non-templated function, while other declarations can be safely removed without affecting the bug. No clue |

Posted in reply to d-bugmail | http://d.puremagic.com/issues/show_bug.cgi?id=2436 ------- Comment #3 from bugzilla@digitalmars.com 2009-02-16 19:35 ------- I tried linking this obj file, and it linked without complaint, and runs printing "Test". I suspect the problem may be with multithreading on a multicore system. My system is single core. If you're running multicore, is there a way to use only one core and try it that way? -- |
