Bug #: 11362
Summary: Undefined behavior in pop_heap_comp.pass.cpp
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
I was running the libcxx tests with gcc-4.7.0 and noticed:
% c++ -std=c++11 pop_heap_comp.pass.cpp
% ./a.out
*** glibc detected *** ./a.out: double free or corruption (out):
0x0000000002443010 ***
This is because of:
std::pop_heap(ia, ia, std::greater<int>());
delete [] ia;
(ia, ia) is not a valid range and will send the ia pointer to lala land.
