Bug #: 14294
Summary: std::deque clear() (and destructor too) segfaults
because begin() > end()
Product: libc++
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: All Bugs
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
It seems to me looking at it under the debugger, that the problem is somehow _i
(begin) starts further than _e (end) therefore _i is never equal to _e and the
loop continues until it segfaults. This is the problematic loop in file deque,
but obviously the problem is somewhere else.
template <class _Tp, class _Allocator>
void
__deque_base<_Tp, _Allocator>::clear() _NOEXCEPT
{
allocator_type& __a = __alloc();
for (iterator __i = begin(), __e = end(); __i != __e; ++__i)
This is for a deque of pointers, so the problem is not in a user destructor.
