problems while parsing boost-library headers

[tlik]

Environment

• OS and Version: Ubuntu 20.04.6 LTS
• VS Code Version: 1.93.0
• C/C++ Extension Version: 1.21.6

Bug Summary and Steps to Reproduce

The problem occurs when I add "boost/accumulators" headers (boost version 1.81) and try to use some stuff. From this moment on, the "C/C++" extension hangs in the "project scanning" mode (tooltips, auto-completion, auto-formatting stop working). At the same time, I see that the cpptools-srv process memory consumption is constantly growing (can eat 20 gigabytes in less than a minute).

This issue can be reproduced with the following simple test project

#include <boost/accumulators/accumulators.hpp>
#include <boost/accumulators/statistics/mean.hpp>

int main() {
   using namespace boost::accumulators;
   accumulator_set<double, features<tag::mean>> accumulator;
}

Hi @tlik,

I just tried to reproduce this issue on Ubuntu 22.04 (with boost 1.86.0) and was unsuccessful. I'll try again with an older version of Boost, but if there anything else going on in your workspace that you can share to help us see the issue, please let us know.

Please also note that the extension should already be adding /usr/local/include to the includePath based on the compiler you selected (gcc-10). You should remove those from your configuration.

I was also unable to reproduce the issue with Boost 1.81.0.
