ghci compacting gc crash: `internal error: update_fwd_large: unknown/strange object 24`
[T2.hs](/uploads/ba8d7dd78502eb7d43f64ead956047de/T2.hs)
when the example above is loaded into ghci with compacting gc: `echo main | ghci-head T2.hs +RTS -c -RTS`, it crashes with:
```
GHCi, version 10.1.20260623: https://www.haskell.org/ghc/ :? for help
Using default language edition: GHC2024

ghci> <interactive>: internal error: update_fwd_large: unknown/strange object 24
(GHC version 10.1.20260623 for x86_64_unknown_linux)
Please report this as a GHC bug: https://www.haskell.org/ghc/reportabug
Aborted (core dumped) echo main | ghci-head T2.hs +RTS -c -RTS
```
it runs fine under ghci with default copying gc, or with compiled object code, and produces the right result `154000000`.
reproducible on x86_64-linux with current head commit 44309cd377f115d3e6b788097750bd534b47f3e4.
