Bug ID: 109920
Summary: value-range.h: Mismatched new [] and delete
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
I just did a valgrind build of gcc trunk. It said
=91612== Mismatched free() / delete / delete []
==91612== at 0x484498A: operator delete(void*, unsigned long)
(vg_replace_malloc.c:1072)
==91612== by 0x18D285B: ~int_range (value-range.h:493)
==91612== by 0x18D285B: ~Value_Range (value-range.h:516)
==91612== by 0x18D285B: ranger_cache::fill_block_cache(tree_node*,
basic_block_def*, basic_block_def*) (gimple-range-cache.cc:1479)
Source code is
inline void
irange::maybe_resize (int needed)
{
if (!m_resizable || m_max_ranges == HARD_MAX_RANGES)
return;
if (needed > m_max_ranges)
{
m_max_ranges = HARD_MAX_RANGES;
wide_int *newmem = new wide_int[m_max_ranges * 2];
memcpy (newmem, m_base, sizeof (wide_int) * num_pairs () * 2);
m_base = newmem;
}
}
template<unsigned N, bool RESIZABLE>
inline
int_range<N, RESIZABLE>::~int_range ()
{
if (RESIZABLE && m_base != m_ranges)
delete m_base;
}
Note use of new [] and delete.
