[8.2] whoops! I'll be damned. It doesn't seem like it should be proper behavior :) sorry. Thanks for the quick reply. If anyone reads this bug, and has a similar problem, the fix for the code above is to change the line to: x myvar = x(y(v)); -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18000 ^ permalink raw reply [flat|nested] 5+ messages in thread
