Bug ID: 89868
Summary: -fsanitize=address inhibits C++ unhandled exception
core dump
Product: gcc
Version: 8.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
Hi!
Noticed that -fsanitize=address appears to inhibit core dump from C++
exceptions. Is there a way to still get the core dump?
The address sanitizer does not catch unhandled C++ exceptions and show a
backtrace etc, but it does cause the core to not be dumped.
Regular compile without Address Sanitizer:
$ g++-8 -Wall -o exception exception.cpp
$ ./exception
terminate called after throwing an instance of 'std::out_of_range'
what(): vector::_M_range_check: __n (which is 0) >= this->size()
(which is 0)
Aborted (core dumped)
$
#include <vector>
int main()
{
std::vector<int> v;
return v.at(0);
}
With sanitizer:
$ g++-8 -fsanitize=address -Wall -o exception exception.cpp
$ ./exception
terminate called after throwing an instance of 'std::out_of_range'
what(): vector::_M_range_check: __n (which is 0) >= this->size() (which is
0)
Aborted
$
