Re: Will the following code cause any memory leak?
"Bill David" <email@example.com> wrote in message
I have the following code in my application. But I find it causes a
serious memory leak with a product we are using. Our application is a
plug-in to this product. But we are not sure what's the boost and stdc+
+ library version included by this product.
The following is the code (On Windows, the product should be written
with Visual Studio 2003/2005):
* @brief Convert modify time string to time_t for easy internal
* @param str Modify time string returned by HTTP server, e.g. "Fri,
18 Jul 2008 11:53:14 GMT"
* @return Corresponding time_t result
time_t parseDate(const string& str)
time_input_facet* timefacet = new time_input_facet("%a, %d %b %Y
%H:%M:%S %z"); // will be automatically deleted by related locale
You claim this memory will be automatically deleted by related locate
object, yet you find there is a memory leak. You are not showing the code
where it is deleted. That is most likely your problem, it is in fact not
ss >> p;
tm t = to_tm(p);
And we find the problem is caused by
time_input_facet* timefacet = new time_input_facet("%a, %d %b %Y %H:%M:
it seems related memory has not been released by locale or some memory
is leaked by time_input_facet.
We have tested above code separately with boost 1.35.0, 1.37.0 and
VS2005 + SP1, it's OK. So can anybody tell me if it's any problem in
above code? Or is it a bug in old version of boost date_time or MS
Visual Studio 2003/2005?
Or is there any other solution to parse a time string like "Fri, 18
Jul 2008 11:53:14 GMT"?
