Jason Kenny commented on TS-4114:
---------------------------------
I was able to get this to build with an older version of of ASAN that comes
with Developer tools v3 from Red Hat. When using a newer version with gcc 5 new
features to report non-freed memory reports issues. The tool in question is
just allocating memory and not freeing it. But given what it does in the build
I can only assume no one thought it would be an issue as it only runs for a
second or so.
The only two way to fix it are :
1) clean up your memory allocs
2) hack the lua custom make file to use different settings when making tools to
build lua
I was more in favor in 1) as it does not require new special logic in the build
files. It also follows what my mom told me, ie put back stuff when your are
done with it. I tend to find that was good advice :-)
