GLH_build() Memory Leak

(1/1)

clarebonk:
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!

xiangjun:
Thanks for reporting the problems you experienced. Could you please be more specific, and better yet, providing me a reproducible example? I will certainly look into it to get it fixed ASAP.

Xiang-jun,  I just sent you an e-mail with an example.  I hope this helps.  Thanks so much.  I'm calling GLH_build an insane number of times, which is the only reason this matters.  But, I'm getting good results!  It is a great software suite.

xiangjun:
I have fixed the memory leak bugs in file rebuild.c. I have also taken this opportunity to tidy up the code base a little bit. Please download the updated version and verify that the bugs are indeed gone.

Thanks,

Xiang-Jun

clarebonk:
It took me awhile to incorporate the new code into my code and to perform regression testing, but it is working perfectly.  No memory leak!  Thanks Xiang-Jun!!
