This is a workaround for the default GitHub Actions runner which inherits to all jobs and steps a SIGPIPE handler that does nothing. The behavior can be reproduced locally by running `trap '' SIGPIPE` and then commands that produce a SIGPIPE signal, like `cat | ls`. The workaround is to compile a C program that resets the SIGPIPE handler and call the mstest command from it. A shell script wrapper like `trap - SIGPIPE ; exec` does not work.
