-Subject: Stack adjustment bug in 'continue' -- gcc 1.10+
-
-Compiling the following simplified program with or without -O produces
-bad code. The 'continue' compiles to a jump to a label which PRECEDES
-the stack adjust for the printf at the end of the loop. This makes the
-stack pointer walk up each time around the loop. If you compile without
--O, "foo" gets allocated on the stack and the debug printf fires.
-Compiled with -O, it coredumps before printing. Compiled on a working
-compiler, it loops forever.
-
-I have installed the bugfix for while loops posted to bug-gcc; it fails
-with or without the bugfix.
