"vector too long" when building and running tests with cmake on Windows using GitHub actions

[cassiebeckley]

The errors look like

[ RUN      ] SpirvReflectMultiEntryPointTest.GetEntryPoint
unknown file: error: C++ exception with description "vector too long" thrown in SetUp().

I haven't been able to reproduce this on my own Windows machine.

Hi, have you solved this problem? I encountered the same issue like this

[cassiebeckley]

No, it hasn't been solved yet. I'll try and look more into it. Would you be able to share which version of Windows and Visual Studio you are using?

Was able to reproduce this issue on a windows machine, but also linux.
The reason is the filepath used to fetch the test content expects us to run the test from the test directory.
If we run it from the wrong directory, the file fails to open, and tellg returns -1, which is then passed to vector::resize without checking, causing the vector too long error.
