Bug ID: 392336
Summary: libclang crashes on C++ project and kdevelop follows
with double free or curruption
Product: kdevelop
Version: 5.2.1
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Language Support: CPP (Clang-based)

console output on the crash.
I have an annoying Crash on C++ project. I have Kdevelop 5.2.1 running on my
Fedora machine from the repos and also in a VM as AppImage on Ubuntu 16.04 and
both crash when indexing/parsing the source.
The project is https://github.com/riebl/vanetza on commit
c33b7f6c9d5bed49a5dfbb948963a9895a144129.
As soon as I add the project to a kdevelop session its being indexed and at
some point inevitably crashes before finishing the parsing.
First I get the output from a libclang crash and the I get either "double free
or corruption (!prev)" or "corrupted double linked list". I have the full
commandline output of the first one appended.
libclang: crash detected during parsing: {
'source_filename' : '<arbitrary
path>/vanetza/vanetza/geonet/data_request.cpp'
'command_line_args' : ['clang', '-ferror-limit=100', '-fspell-checking', '',
'-Wunused-parameter', '-Wunreachable-code', '-Wall', '-std=c++11', '-nostdinc',
'-nostdinc++', '-xc++', '-isystem/usr/include/c++/7',
'-isystem/usr/include/c++/7/x86_64-redhat-linux',
'-isystem/usr/include/c++/7/backward', '-isystem/usr/local/include',
'-isystem/usr/lib64/clang/4.0.1/include', '-isystem/usr/include', '-imacros',
'/tmp/kdevelop.rA5119'],
'unsaved_files' : [],
'options' : 781,
}
I really like KDevelop and use it for all my cmake related proejcts and most
other in regard to C/C++.
