Hi. I had the same problem some days ago with and old version of gcc. I changed to a newer version (3.3.5) and everything worked ok. If you don't want to upgrade, look at the source code of lwgeom_gist.c, you will see a couple of preprocessor directives around those lines, to differenciate between version >=
8.2 and < 8.2 of postgres, with an if, else and endif. Just remove those directives and leave the code in the section corresponding to your case (<8.2)<br><br>After changing that, I think the same thing occurs again somewhere else in lwgeom_gist.c. Do the same there.
