stg_ap_pp_ret

[Frederik Eaton]

Hi Simon,

No time to try to reproduce it, I'm preparing for a conference ;)

I haven't seen the bug recently, but ... tangentially I was musing
that if someone could devote some time to turning the GHC internal
error message (which I've seen on over a hundred occasions, I'm sure)
into a tool that queries the user and then, if he is OK with sharing
his code (as a quite large number of programmers are) sends a core
dump of GHC into some repository to be analysed, it might be
beneficial for the GHC development process in the long run. This
concept probably has a standard name that I don't know - I think
something vaguely similar was done with some web browsers once,
although perhaps not with the entire program state. It sounds like it
might be difficult to implement, though. Just a thought.

Cheers,

Frederik
