------- Comment #10 from aldot at gcc dot gnu dot org  2008-01-11 13:30 -------
Still fails for me on trunk (revision 131461):

gcc-4.3-HEAD -Os --combine -c -o pr28779.o pr28779a.c pr28779b.c
pr28779b.c: In function 'e1000_write_reg_io':
pr28779b.c:12: internal compiler error: in cgraph_estimate_size_after_inlining,
at ipa-inline.c:188
