Description Craig Tenenbaum 2015-11-10 23:53:16 UTC

I've had this issue occur under a varying number of circumstances but have attempted to reduce them to something of a minimal case that should have an obvious justification. It looks like something's going awry in KDevelop's Clang cursor dispatch since it seems to be trying to visit a base class which won't yet be instantiated and thus crashing?

While this BT was produced using an SVN snapshot of Clang 3.8, I've seen this error sporadically going at least as far back as Clang 3.6. This is the first time I've tried to find a formulation which seems to reliably reproduce the crash since it comes more-or-less directly from an actual piece of code I'm trying to use in a project. The justification of the (hopefully attached) minimal case is that this is, in fact, how GCC even writes some of their traits classes. It allows you to compose traits from traits you've already written in a pretty simple fashion.

Reproducible: Always

Steps to Reproduce:
1. Try to input intended minimal case, which will be attached.
2. It generally crashes for me about the time I get to '::ty' in on line 6 as a part of "class IsSafeConversion : public std::is_same<T, typename std::common_type<T, U>::ty"


Expected Results:  
Even if this a horribly bad design, even if it's somehow wrong in some obvious way I'm not seeing, I don't think this should instigate a crash.

In case this might be relevant

Comment 4 Kevin Funk 2015-11-11 08:04:36 UTC

Can't reproduce using Clang from Git as of 6 days ago [1]. Tried running your example through duchainify (a kdevplatform utility for running) & KDevelop itself.

For the record, you're also missing debug symbols for KDevelop (no line numbers from kdevclangsupport.so), please install them.

[1] * cca12de - (HEAD -> master, origin/master, origin/HEAD) Use profile data template file for covmap func record (NFC) (6 days ago) <Xinliang David Li>

Still producing it with the specified commit and newer.

Comment 8 Milian Wolff 2015-11-12 12:42:24 UTC

I cannot reproduce this issue btw. with clang 3.7 and kdevelop built from the 5.0 branch.

Relevant part of the backtrace:

The code looks OK, I'd say. Could you by any chance run kdevelop through valgrind and see if it spits out something useful?

valgrind --smc-check=all-non-file --track-origins=yes kdevelop -s ...

Ah, now I triggered it by invoking code completion within the template class:

Comment 10 Milian Wolff 2015-11-12 12:54:27 UTC

commit 8098dc5a91baa54b219179e03ea5b19f6350e395
Author: Milian Wolff <mail@milianw.de>
Date:   Thu Nov 12 13:50:29 2015 +0100

    Fix crash when invoking code completion inside complex template class.
    
    Apparently we sometimes fail to resolve a template parameter.
    For now, fix the crash but probably we need to resolve the
    actual bug elsewhere.

Comment 11 Craig Tenenbaum 2015-11-12 23:17:16 UTC

Yep, this fixed it, sorry for the initial confusion and thank you. :D
