Why did you remove -j1 from the b2 invocations in this PR? This leads to sporadic failures in test_xml_parser_rapidxml.

Ah, sorry. I couldn’t find anything in the commit message and guessed it might have been related to old bugs that should have been fixed by now.

The problem is that test_xml_parser_rapidxml.cpp writes out xml files with fixed names, so when two instances of this test are run in parallel, they step on each other's toes. To remove -j1 the test needs to be fixed to not do that, e.g. by adding a random prefix to the file names, or by using a temporary directory with a random name.

It might be as simple as adding random prefixes to the file names passed to this function:

property_tree/test/test_utils.hpp

Lines 108 to 116 in 5c5e2c9

	// Create test files
	test_file file_1(test_data_1, filename_1);
	test_file file_2(test_data_2, filename_2);
	test_file file_out("", filename_out);
	rf(filename_1, pt); // Read file
	wf(filename_out, pt); // Write file
	Ptree pt2;
	rf(filename_out, pt2); // Read file again

I can test it, and if it doesn't work, we can settle for adding -j1 because I doubt it's worth putting in more time, as we don't frequently make changes to this repository.

I already put back the -j1 to fix the CI failures, but we can in principle apply this fix, if it works.
