Simon Jakobi pushed to branch wip/sjakobi/T17088 at Glasgow Haskell Compiler / GHC Commits: 95150960 by Simon Jakobi at 2026-07-21T18:39:00+02:00 testsuite: Run T17088 only with compacting GC T17088 is a regression test for #17088, a pointer-tagging bug in the compacting collector. Restore its original single-way scope, which was lost when the test was converted to use the compacting_gc way. The reproducer reads and prints an uninitialized byte array, so its stdout is not stable. Ignore stdout while retaining checks for crashes and other failures.
