Reproduction for ghc#23313.
I generate the data file with gvim data/big.csv with the vim command
:0put=range(1,100000).
I only see the problem on the ghc-9.4.* versions. I've not seen it with
ghc-9.2.7, ghc-8.10.7 or ghc-9.6.1. Only fails if optimization is off
(with -O0). To keep the data file small for the reproducer, I've shrunk the
stack size to 16M, down from the default (ghc is compiled with
-with-rtsopts=-K512M).
