Comment 1 Milian Wolff 2011-08-27 02:09:26 UTC

please run kdevelop through valgrind and show us the output:

valgrind --track-origins=yes --num-callers=25 kdevelop

Comment 2 Milian Wolff 2011-08-28 13:52:27 UTC

Aleix, I just had a look at the sources:


bool OptionAst::parseFunctionInfo( const CMakeFunctionDesc& func )
{
    if(func.name.toLower()!="option" || (func.arguments.count()<2 && func.arguments.count()>3))
        return false;
    ...

the || (...) stuff is always false as func.arguments.count() cannot be <2 && >3! This is most definitely an error which could lead to crashes like the above in the following code in release-builds.

Comment 3 Nils Larsson 2011-12-08 17:07:24 UTC

Completly forgot about this one. Sorry.

Anyway, I havnt triggerd it in ages, so WORKSFORME now?

Comment 4 Milian Wolff 2011-12-13 17:12:54 UTC

not closing it until aleix commented on my "code review" - there is an error there as far as I saw the last time (see above)

Comment 5 Aleix Pol 2011-12-13 17:17:09 UTC

Git commit 1bb44fda994a15846fb3107bc3afa0fed818d00b by Aleix Pol.
Committed on 13/12/2011 at 18:16.
Pushed by apol into branch 'master'.
