Failure to embed large files with -O0 on GHC 9.4, Mac OS X

[csasarak]

Hi, I've found that when I try to build file-embed using GHC 9.4 with -O0 compilation fails when using a file > ~20MB in size. I get this error from the compiler:

$  cabal build test

I've made a sample using file-embed's tests to demonstrate this behavior here that you can try yourself.

1. Check out the branch here
2. Find (or make: dd if=/dev/zero of=./zero_data bs=1024 count=20000) a file ~20MB or greater.
3. Provide an absolute path to the file from step 2 here.
4. Run cabal build test

Altering the cabal.project file to have optimization: 1 (or no optimization directive at all) and running cabal build test will resolve this problem.

Other things I've checked:

1. I added traces in the code and found that it is indeed using bytesPrimL from Use TH 2.16 Bytes literal (#24) #36 in bsToExp.
2. Compiling with -O0 and -ffull-laziness is also successful.

This may be a bug in the compiler, but I wanted to ask here. Thank you for maintaining this package. Please let me know if there's any additional info I can provide.

Best wishes,
