Bug ID: 360707
Summary: KDevelop crashes during parsing a project when it is
compiled with GCC 6.0
Product: kdevelop
Version: 4.90.91
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: grave
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: jgrul...@redhat.com
Reproducible with KDevelop 4.7.3 or KDevelop 5.0 beta. We now have GCC 6.0 in
Fedora 24 and this makes KDevelop unusable.
Relevant information from GCC release notes:
Value range propagation now assumes that the this pointer of C++ member
functions is non-null. This eliminates common null pointer checks but also
breaks some non-conforming code-bases (such as Qt-5, Chromium, KDevelop). As a
temporary work-around -fno-delete-null-pointer-checks can be used. Wrong code
can be identified by using -fsanitize=undefined.
I tried to use "-fno-delete-null-pointer-checks" and that solution worked for
me. I can workaround this temporarily for our Fedora packages, but this should
be rather fixed in KDevelop itself.
Reproducible: Always
