Bug ID: 431811
Summary: KDevelop crashes when parsing projects that use
wxWidgets-3.1.4
Product: kdevelop
Version: git master
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: kogiokkaf...@gmail.com
Target Milestone: ---
Created attachment 134991
--> https://bugs.kde.org/attachment.cgi?id=134991&action=edit
An wxWidgets example project for reproducing the bug
SUMMARY
KDevelop crashes when parsing projects using wxWidgets-3.1.4, but has no issue
with projects using wxWidgets-3.0.4. I'm not sure if there are any more
libraries will cause this issue.
STEPS TO REPRODUCE
1. Get wxWidgets-3.1.4. I built the library from source.
2. Create CMake cache of the attachment project with "cmake -Bbuild
-DCMAKE_PREFIX_PATH=<path-to-wxWidgets-3.1.4>"
3. Execute "kdevelop --ps" and Create New Session
4. Open Project and choose the attachment project
5. Before the parsing is finished, KDevelop will crash silently
OBSERVED RESULT
I did some tests and found out that it is caused by
"clang_getFieldDeclBitWidth" in "plugins/clang/duchain/builder.cpp":
https://invent.kde.org/kdevelop/kdevelop/-/blob/e2595310efbd6ec5f9c3c1ce49b46d80b07aecb7/plugins/clang/duchain/builder.cpp#L1090
If I change
decl->setBitWidth(clang_getFieldDeclBitWidth(cursor));
to
decl->setBitWidth(-1);
, KDevelop will finish the parsing without issue.
