We may change the global environ variable in the child; when using vfork() this also sets it in the parent. Preserve the parent's environ in child_execute_job() so it takes effect for all callers. Reported by Denis Excoffier <bug-tar@Denis-Excoffier.org> Root cause found by Martin Dorey <Martin.Dorey@hitachivantara.com> * src/job.c (start_job_command): Remove save/restore of the parent environment. (child_execute_job): Add save/restore of the parent environment, if we use vfork(). * tests/scripts/functions/shell: Add a test the crashes if we don't reset environ after we run $(shell ...). |
