[clazy] [Bug 388925] New: Segmentation fault in Expr::getBestDynamicClassTypeExpr()
https://bugs.kde.org/show_bug.cgi?id=388925 Bug ID: 388925 Summary: Segmentation fault in Expr::getBestDynamicClassTypeExpr() Product: clazy Version: unspecified Platform: Ubuntu Packages OS: Linux Status: UNCONFIRMED Severity: crash Priority: NOR Component: general Assignee: unassigned-b...@kde.org Reporter: tom.isaac...@navico.com CC: smart...@kde.org Target Milestone: --- I'm running clazy-standalone on my codebase and it keeps crashing. The stack showed me it was crashing while calling Expr::getBestDynamicClassType() from OldStyleConnect::fixits() and I was able to confirm this by adding debug output. I'm wondering if this is https://www.mail-archive.com/llvm-bugs@lists.llvm.org/msg16745.html so I tried recompiling clazy with clang 6.0 but I'm having trouble. I've built the clang source myself but there doesn't seem to be a way to override FindClang.cmake with my build directory rather than Ubuntu's default clang 3.8 install. Do I have to edit the cmake build myself? -- You are receiving this mail because: You are watching all bug changes.
