I discovered following internal compiler error in gcc 4.3.0 (trunk). The cause is the svn change 125925.
The title sounds to be similar to bug 34018, but the removal of change 125925 does not help for bug 34018. So this bug must be something different. gcc version: gcc 4.3.0 svn revision 125925 and later at least with gcc 4.3.0 svn revision 129958 (20071107). $ gcc -v Using built-in specs. Target: x86_64-unknown-linux-gnu Configured with: ../configure --prefix=...my_path... --enable-shared --with-gmp=...my_path... --with-mpfr=...my_path... --enable-languages=c,c++ Thread model: posix gcc version 4.3.0 20071107 (experimental) (GCC) steps to reproduce: $ gcc -O2 -c testcase.c testcase.c: In function 'checkVersionLibtestcase': testcase.c:10: error: invalid array index 20 - (<unnamed-signed:64>) &version_testcase; testcase.c:10: internal compiler error: verify_stmts failed Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. Exit 1 Without optimization it compiles fine: $ gcc -c testcase.c Commenting out change 125925 also compiles fine (patch attached). -- Summary: internal compiler error: verify_stmts failed Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: holger dot hopp at sap dot com GCC build triplet: x86_64-unknown-linux-gnu GCC host triplet: x86_64-unknown-linux-gnu GCC target triplet: x86_64-unknown-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34029
