Memory debugging [message #1792143]

Hi

I'm looking to use auto-generated C code to give a perhaps 10 fold speed up wrt EMF-Java for model to model transformations. It is perhaps 15 years since I was a good C++ programmer and 25 since I wrote serious C, so my first experiments bring back some unpleasant memories best summed up by my then advice to colleagues.

"You cannot develop code with non-trivial patterns of memory allocation without using Purify".

Sadly Purify has steadily deteriorated since its initial release; I still rate it as the best software I have ever used. Purify's underlying technology is fundamentally fragile mandating yearly payments which are far too high for consideration for Open Source development and it is not clear that Eclipse+MinGW is supported at all.

Is there a recommended memory debugging approach for use with CDT?

(Since I am auto-generating C, I can tolerate very heavy auto-generated instrumentation in a debug mode.)

Regards

Ed Willink

I'd have said Valgrind but I don't think it works under Windows.
If cost is really a concern, perhaps you might want to be the one to port it.

This is off topic for this forum which is devoted to CDT issues.
You should try asking at places like stackoverflow.com
But then, they don't seem to like the question much.

Hi David

Thanks for the good links - many (unattractive) options to think about. Probably time for an alternate Linux boot on my tower.

"off-topic". I was hoping that someone would embarrass me by pointing out a launch configuration checkbox. Memory debugging seems like something CDT could offer out of the box.

Regards
