Title: GLH_build() Memory Leak
Post by: clarebonk on May 15, 2009, 09:11:20 pm: I took out the printf()s from GLH_build() and hard coded the user-response values that I want, so that I do not have to enter them in every time I run the function. When I call GLH_build() in a loop, my memory usage increases with each iteration. I assume this behavior is not wanted. There seems to be a memory leak somewhere. I tried looking through the code to make sure the mallocs are all freed, but I have not found any red flags. Any idea why/where this is happening?

Thanks!

Thanks,
