Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
This file comes from tcl8.6.1/pkgs/sqlite3.8.0/generic/tclsqlite3.c.
Again, this is not reproducible with -O1, therefore it is an optimizer problem.
