Comment:
It works after this partial reversion:
{{{
Mon Dec 15 02:02:21 PST 2008 Simon Marlow <[email protected]>
* Revert CorePrep part of "Completely new treatment of INLINE
pragmas..."
The original patch said:
* I made some changes to the way in which eta expansion happens in
CorePrep, mainly to ensure that *arguments* that become let-bound
are also eta-expanded. I'm still not too happy with the clarity
and robustness fo the result.
Unfortunately this change apparently broke some invariants that were
relied on elsewhere, and in particular lead to panics when compiling
with profiling on.
Will re-investigate in the new year.
