The only way the ping-pong would lead to this behavior woudl be if you had a self-referring (ie recursive) expression. ie, a PLUS_EXPR where one of the operands is the PLUS_EXPR itself. More likely it's something wonky elsewhere. That's been the pattern so far. jeff -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26348
