Bug ID: 77268
Summary: Vector erase call destructor for last element twice
and doesn't call destructor for eased element.
Product: gcc
Version: 6.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: jdinardo at nycap dot rr.com

Small 33 line program which shows the problem.
Vector erase is asked to erase 3rd element of 5 element vector. The
destructor for the last(fifth) element is called twice and the destructor
for the 3rd element is not called. The 3rd element is erased but the malloced
memory is never freed. BUG 47305 seems to imply that this is ok. If that is the
case, then pleas ignore this.
