I had difficulties with electric-fence, but boehm-gc---even if memory
leaks are not its primary goal---has worked for NetBSD compiled
programs.

But to use it, the source (in my case the whole KerGIS system) must be
sufficiently organized so you can insert the headers at the articulation
of the code: after external dependencies, before internal stuff. And
since boehm is a garbage collector, some acrobatics with memory, even if
legitimate if one knows what one is doing, can cause some problems. But
that's another story.
