Summary: g++ with -O3 enters infinite loop
Product: gcc
Version: 4.5.1
Status: UNCONFIRMED
Severity: normal
Priority: P3

The program for which the bug applies.
$ x86_64-redhat-linux-g++ sudoku_solver_single.cpp -O3 -o sudoku_solver_single
$ ./sudoku_solver_single
.923.........8.1...........1.7.4...........658.........6.5.2...4.....7.....9.....
The program seems to enter an infinite loop inside solve, even though found_one
is set to true. The expected behaviour is observed when -O2 is used instead.
