Null reference exception when parsing header

[mydogisbox]

This issue is nearly identical to:
#66
I verified I have the fix for issue 66.

Minimal test case:

#include <sstream>

class octave_pager_stream : public std::ostream { };

I have pushed a parser fix for this issue. Unfortunately your test case also exposes another issue in the generator which does not cope well yet with classes inheriting from templates (std::ostream seems to be typedef'd template).

Fixing the rest of issue in the generator is non-trivial and I'll probably only be able to get to it in a few days. You can ignore it for now with something like: lib.IgnoreClassWithName("octave_pager_stream"); in Preprocess.

Thanks a lot for the responsive fixes!

[mydogisbox]

Is there a list of things which still need to be fixed for this bug?

[tritao]

Some minor improvements were done a couple days ago to this area so you don't need IgnoreClassWithName anymore.

But proper support for this is still missing, basically classes need to be able to inherit from templates, I haven't looked into this yet so I don't know how much work it is.

Is this a big issue for you?

[mydogisbox]

Out of the 700+ classes in the project (Octave) I'm trying to wrap, fewer than a dozen don't inherit from templates or depend on a class which does.

[mydogisbox]

Just FYI to prevent duplicate work, I've started working on this issue.

[tritao]

Thanks, let me know if you have any questions or need any guidance.

[mydogisbox]

I haven't made much progress on this and am very busy as the moment. i.e. if you're wanting this done in a timely manner, someone else should do it, otherwise I'll get back to it eventually.

[tritao]

Could you re-test this with an up to date version of CppSharp?

[mydogisbox]

I will, but I haven't had a chance to get https://groups.google.com/forum/?hl=en#!topic/cppsharp-list/TD6Vur9Zboo resolved, so I may not be able to fully test it.

[mydogisbox]

@tritao The brief bit I can test works, but I'm blocked by the above issue in clang, so all I can say is that it no longer crashes on the template inheritance.

[tritao]

I tried to reproduce the issue with clang-cl and the code you posted on the list, but I was not able to make it crash.

I would open an issue about it in the Clang bug tracker. Unless it gets reported, it won't get fixed.

[mydogisbox]

I tried to reproduce it with clang-cl as well, but was likewise unable to reproduce it. I haven't logged it because I'm not really sure what to report without a minimal test-case. Any suggestions?
