[Git][ghc/ghc][master] 2 commits: rts: handle large AP closures in compacting GC
Marge Bot pushed to branch master at Glasgow Haskell Compiler / GHC Commits: cca0d589 by Luite Stegeman at 2026-06-30T13:33:40-04:00 rts: handle large AP closures in compacting GC The function update_fwd_large in the compacting GC could run into an unexpected object with the following error: internal error: update_fwd_large: unknown/strange object 24 Closure type 24 is the AP closure, which was not handled in upd_fwd_large. This patch adds handling them. fixes #27434 - - - - - 42935858 by Luite Stegeman at 2026-06-30T13:33:40-04:00 testsuite: use compacting_gc way instead of hardcoding +RTS -c - - - - - 5 changed files: - + changelog.d/fix-compacting-gc-ap-27434 - rts/sm/Compact.c - + testsuite/tests/rts/T27434.hs - + testsuite/tests/rts/T27434.stdout - testsuite/tests/rts/all.T Changes: ===================================== changelog.d/fix-compacting-gc-ap-27434 ===================================== @@ -0,0 +1,11 @@ +section: rts +synopsis: Fix "unknown/strange object 24 crash" in compacting GC +issues: #27434 +mrs: !16261 + +description { +Fix a crash in the compacting garbage collector when collecting large +function-application thunks.
