Bug ID: 100984
Summary: gimple-ssa-evrp.c: mismatched new and delete
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
I have just done a valgrind build of gcc trunk and it says:
==279305== Mismatched free() / delete / delete []
==279305== at 0x48434DD: operator delete(void*) (vg_replace_malloc.c:802)
==279305== by 0x14B0691: ~pointer_equiv_analyzer (gimple-ssa-evrp.c:168)
==279305== Address 0x133d9a40 is 0 bytes inside a block of size 32 alloc'd
==279305== at 0x4842103: operator new[](unsigned long)
(vg_replace_malloc.c:579)
==279305== by 0x14B0CB7: pointer_equiv_analyzer (gimple-ssa-evrp.c:163)
Source code is
pointer_equiv_analyzer::pointer_equiv_analyzer (gimple_ranger *r)
{
m_ranger = r;
m_global_points = new tree[num_ssa_names] ();
}
pointer_equiv_analyzer::~pointer_equiv_analyzer ()
{
delete m_global_points;
}
Suggest use [] on delete.
