Running nimble test on a project fails with a compilation error, whereas with 2.2.4 the tests built and ran successfully.

Here is an extract from the output, showing where it fails:

and the config.nims just contains


switch("path", "$projectDir/../src")

The test was run on Linux Mint:

and GCC version information is:

Can anyone suggest why this failure is happening? I haven't included details of the actual project where the tests are, as there's too much code to post and the error appears related to compiling system.nim, so seems unrelated to the specifics of the project.
