State-Changed-From-To: open->closed State-Changed-By: paolo State-Changed-When: Thu Oct 31 12:39:09 2002 State-Changed-Why: User error. In test::init you need 'resize' NOT 'reserve': only the former changes the size of the vector, whereas the latter its capacity. Definitely, before *assigning* the elements of the vector you need it to have two elements, *not* just having it allocated raw memory capacity to grow to a maximum size of two without reallocations. I suggest reading C++PLSE, §16.3.8. Thanks for your report, Paolo. http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=7974
