cpptools-srv SIGSEGV on Linux while editing C++ file(s) #14819
Description
Activity
Unfortunately, I can't attach the C++ .hpp file itself as it contains copyrighted code. However, it is fairly complex C++23 syntax sugar involving classes, lambdas, and so on. The core file is generated when I open the file in the editor, make adjustments to the code (or not), and then save it. In fact don't need to edit or save, just open that file and core is generated.
With the following stack trace:
Core was generated by `/home/user1/.vscode/extensions/ms-vscode.cpptools-1.34.4-linux-x64/bin/cpptools-srv 146908 {F62895D2-8355-417E-B211-FCBCAA32E8A7}'.
Program terminated with signal SIGSEGV, Segmentation fault.
