security/DOS implications.
Hi,
Since this can be a security issue, I'd recommend also issuing patches
that apply to older compilers, so that distributions can apply them/make a
security advisory/etc. No need for a full release of (e.g.) ghc 6.12, but
a "blessed" patch for it would be welcome. I'm picking on 6.12 mostly as
Debian stable and Ubuntu Lucid (LTS) ship it.
thanks!
