MALLOC_TRACE for Windows

Question

In our company we have an inhouse framework similar to the mtrace (MALLOC_TRACE) functionality in glibc for detecting memory leaks. This framework is written to run on Windows, but it doesn't work very well in GNU/Linux.

So, do anybody know of a portable equivalent to mtrace (MALLOC_TRACE), that can run on Windows, GNU/Linux and hopefully even MacOSX?

Answer 1

Did you tried dmalloc?

perhaps I think on linux valgrind is much better

Answer 2

A few month ago, I developed the base for a portable C library, allowing some kind of OOP.

Memory is managed with reference counting, and the project includes a memory debugger, that keep track of all allocations, providing extended debug informations when necessary.

It's published under the BOOST license, so you're free to use it.

Current revision is actually in a non-workable state, but you may check older ones, to see how it's done.

A working version is available in the tags (1.2.2-0). This one builds fine on OSX, Windows and Linux.

Memory stuff is located mainly in the source/core directory:

• XSMemory.c
• XSMemoryDebug.c
• __XSMemory.c
• __XSMemoryDebug.c

Here's the kind of output for a SegmentationFault, for instance:

You can then get backtrace informations, display allocations, etc.
