--- Comment #10 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #8) > Note that this first started to ICE with r223470, which is also the first > revision where it starts opening cmds-check.c (which also premature to me, > because no warning is actually emitted; I'd think that it should do that > only if the warning is actually going to be emitted and needs it, otherwise > it is an unnecessary compile time slowdown); that ICE got later fixed in > r224236, but later reappeared (in r230331). I also don't think this is the same ICE that Marek fixed. It is likely that David's changes altered something in the way the line-table is constructed and this uncovered a different latent bug.
