Difference between optimized and non-optimized version

[Mitar]

Hi!

I am attaching a program which locks (throws an exception <<loop>>)
when compiled like:

ghc --make -threaded -main-is Test.main Test.hs -o test

and doesn't lock when compiled with

ghc --make -threaded -main-is -O2 Test.main Test.hs -o test

This should probably not happen.

I am using 6.12.3 on Linux x86_64.

Best regards
