------- Comment #1 from burnus at gcc dot gnu dot org 2008-08-25 08:21 ------- Presumably a duplicate of PR 37217 even though the reduced test case there does not give an ICE here.
$ gcc -Wconversion regcomp.i gives the ICE. I defer from attaching the rather large regcomp.i.gz, unless someone wants to see it. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37230
