bad_alloc occuring when allocating small structs
- by SalamiArmi
A bad_alloc has started showing up in some code which looks perfectly valid to me and has worked very well in the past. The bad alloc only occurs once every 50-3000 iterations of the code, which is also confusing.
The code itself is from a singly linked list, simply adding a new element to the queue:
template<typename T> struct container
{
inline container() : next(0) {}
container *next;
T data;
};
void push(const T &data)
{
container<T> *newQueueMember = new container<T>;
//... unrelated to crash
}
Where T is:
struct test
{
int m[256];
};
Changing the size of the array allocated array to anything but very small values (1-8 ints) still results in a bad_alloc occasionally.
A few extra notes about my program:
- I used Poco::ThreadPool to thread my program. I've only recently added this functionality, before I had it running with Win32 threads. However, only the main thread ever calls push().
- I am also occasionally getting other crashes which could be related. However, when I try to debug with visual studio 2008, I can't navigate back to the call stack, or the crash happens deep within new().
Thanks in advance.
