--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to nightstrike from comment #3) > Seeing as how this is a testsuite issue, it seems that the crash in the same > location applies to the following: > FAIL: gcc.dg/vect/slp-reduc-10a.c (internal compiler error: in build2, at > tree.cc:5097) > FAIL: gcc.dg/vect/slp-reduc-10b.c (internal compiler error: in build2, at > tree.cc:5097) > FAIL: gcc.dg/vect/slp-reduc-10c.c (internal compiler error: in build2, at > tree.cc:5097) > FAIL: gcc.dg/vect/slp-reduc-10d.c (internal compiler error: in build2, at > tree.cc:5097) > FAIL: gcc.dg/vect/slp-reduc-10e.c (internal compiler error: in build2, at > tree.cc:5097) What is interesting is these testcases already use __SIZETYPE__ in some places but not all. Like someone tried to fix them up when they committed them but not all the way.
