Hmm the testsuite also gave an error actually?:

Test suite failure for package sexp-grammar-2.3.3
    sexp-grammar-test:  executable not found
Full log available at /var/stackage/work/unpack-dir/.stack-work/logs/sexp-grammar-2.3.3-test.log

Test suite executable "sexp-grammar-test not found for sexp-grammar:test:sexp-grammar-test   
Possible causes of this issue:                                                                                              
* No module named "Main". The 'main-is' source file should usually have a header indicating that it's a 'Main' module.
* A cabal file that refers to nonexistent other files (e.g. a license-file that doesn't exist). Running 'cabal check' may po
int out these issues.

Not sure why this happened now.

Hm... Thanks. I'm having a look

@juhp I believe I've fixed the overlapping instances issue by adding some CPP in 033ea421ae0422a299116697d8b999239b66733f.

W.r.t. the testsuite issue, I am not sure what happened there, too -- I can't reproduce it neither with stack and nightly resolver nor with cabal. Is there anything useful in the logs?

[juhp]

Not that I know - you/we can try to re-enable the testsuite in Stackage if you wish.

[esmolanka]

Thanks -- I'll do a pull request re-enabling both the test suite and the benchmark, then.
