If you compile the testcase consisting of files testsuite/gcc.dg/lto/20081115_[012].c with disabled early inlining (-fno-early-inlining), the execution will abort.
The testcase is full of extern inline functions so probably the correct ones get picked by early inliner but wrong ones by the IPA inliner. -- Summary: gcc.dg/lto/20081115_?.c fails without early inlining Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: lto AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jamborm at gcc dot gnu dot org GCC build triplet: i686-pc-linux-gnu GCC host triplet: i686-pc-linux-gnu GCC target triplet: i686-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43577
