[Bug c/40255] New: internal compiler error: in root_var_init, at tree-ssa-live.c:1034
When compiling the Cuba library from http://www.feynarts.de/cuba/ version 1.6 with gcc 4.2.4 I get: ./src/divonne/Explore.c: In function 'Explore': ./src/divonne/Explore.c:17: internal compiler error: in root_var_init, at tree-ssa-live.c:1034 The problem is specific to gcc 4.2.4 (it does not appear with 4.1.2, 4.3.3, or 4.4.0). When -O2 is ommitted from the command line, there is no internal compiler error. -- Summary: internal compiler error: in root_var_init, at tree-ssa- live.c:1034 Product: gcc Version: 4.2.4 Status: UNCONFIRMED Severity: critical Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: sliwa at cft dot edu dot pl GCC build triplet: x86_64-redhat-linux GCC host triplet: x86_64-redhat-linux GCC target triplet: x86_64-redhat-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40255

There are major failures in the lapack 3.1.1 tests with gcc 2.95.3 and in the full range up to gcc 4.2.1.
