Title: cppcheck plugin; SIGSEGV fixed
Post by: blauzahn on February 03, 2019, 02:56:06 PM

The plugin crashed cb when cppcheck has been executed but returns with a failure. This happens e.g. when cppcheck complains about missing std.cfg. I have observed this when using trunk for months on Linux amd64 (e.g. antergos). So, nothing that has changed recently.

The reason for this is a dereferencing nullptr in CppCheck.cpp:332

Code Select


if (nullptr!=resultNode->Attribute("version"))

->* has higher operator precedence than !=

The attached patch changes this to:

Code Select


if (nullptr!=resultNode && resultNode->Attribute("version"))

crashlog including gdb backtrace is attached as well.

If appropriate, can somebody please patch trunk?

Thank you in advance.
