"internal compiler error" while building librump

[Jukka Salmi <j+nbsd%2008.salmi.ch@localhost>]

Hello,

building a release on a i386 system (4.99.72) just failed with an
internal compiler error:

I'm quite sure I can rule out memory problems on the system in question
since it was running fine for years; furthermoer, building again showed
the same problem in the same place.

I'd send a PR about this, but I don't know who's the culprit, thus I
don't know what PR category I should choose...


Any hinta?

Regards, Jukka
