Path of project files corrupted

Type: LanguageService

Describe the bug

• OS and Version: MacOS Mojave 10.14.3
• VS Code Version: 1.31.1
• C/C++ Extension Version: 0.22.0 (Insiders)
• Other extensions you installed (and if the issue persists after disabling them): Cortex-Debug, Python, FreeMarker. Disable does not affect the issue
• A clear and concise description of what the bug is. I am setting up a project as part of migrating from Eclipse. My project build fails with 1000's of unexplained errors. The error messages do not seem reasonable, and when I try to follow through on them, I noticed that the path names the "Problem" reporter refers to is completely broken (corrupted from what is specified in c_cpp_properties.json and the Makefile). Any tips on where to start trouble-shooting this will be much appreciated.

I have inserted two screenshot examples below. Screenshots

Example 1: "/Users/Jack/SSTP/Motor" is my project root, and is prepended to the valid file name that starts at "/Users/Jack/SSTP/STM32"

Example 2: Similar to Example 1, but now the string "__isb" is inserted between the project root path and the file name

Example 3: Similar to 1 and 2, but the string "__IO FLASH_ProcedureTypef ... blah, blah, blah" is inserted in between the two path components.

c_cpp_properties.json

Those errors are not coming from our extension. Do you have another C/C++ extension enabled?

[noppej]

I have no other extensions (apart from the 3 mentioned above). I suspect it has something to do with memory overflows as a result of the 1000's of build errors. It turns out these were caused by a suspect -D generated by STM32CubeMX (incorrect quoting). After fixing that problem, the build errors went away, and my "Problem" paths were no longer corrupted.
I appreciate the clarification that these were not from your extension. That clarification allowed me to look elsewhere.
