[Pkg-haskell-maintainers] Bug#635113: Generated code fails to compile: uses bang patterns without corresponding {-# LANGUAGE BangPatterns #-} pragma

[Josh Triplett]

Package: alex
Version: 2.3.5-2
Severity: grave

The fix for bug 623067 makes alex -g use bang patterns, but doesn't add
the corresponding BangPatterns extension to the list of extensions in
the LANGUAGE pragma at the top of the file.  This makes the generated
code fail to compile:

dist/build/apters/apters-tmp/Scanner.hs:294:18:
    Illegal bang-pattern (use -XBangPatterns):
    ! (base)
