Description

Detected with asan. I think only trunk is affected.

Example: 

Direct leak of 40 byte(s) in 1 object(s) allocated from:
    #0 0x7f67953bbae9 in __interceptor_malloc /build/gcc-multilib/src/gcc/libsanitizer/asan/asan_malloc_linux.cc:62
    #1 0x7f6794fd8d8e in lwpoly_clone_deep /home/raul/dev/public/postgis/liblwgeom/lwpoly.c:231
    #2 0x7f6794fd1298 in lwgeom_simplify /home/raul/dev/public/postgis/liblwgeom/lwgeom.c:1825
