Bug ID: 18282
Summary: When converting std::bind to a std::function, we enter
an infinite loop causing a segmentation fault.
Product: libc++
Version: unspecified
Hardware: PC
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
The following code was posted to stackoverflow giving a segmentation fault with
libc++.
#include <functional>
int main() {
std::function<void(int)> function = [](int) {};
auto binding = std::bind(function, 10);
std::function<void()> jobFunctor = binding; // crashes here with
EXC_BAD_ACCESS
}
>From looking at gdb, it appears that the last line causes an infinite loop of
calls within std::bind until we run out of room on the stack, causing the
crash.
