Bug ID: 61048
Summary: compiling with -fsanitize=address crashes GCC if
pointers are used
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: fab...@ritter-vogt.de
test.cpp:
include <iostream>
int main()
{
int *i = reinterpret_cast<int*>(0xC1000000);
std::cout << *i << std::endl;
}
Compile with:
arm-none-eabi-g++ test.cpp -c -o test.o -fsanitize=address -flto
Link with:
arm-none-eabi-g++ test.o -o test -Wl,-flto
arm-none-eabi-g++ -v:
Using built-in specs.
