+Subject: [PATCH] Fix memory leak in high level API (#781)
+
+Previously, in the high level API if we received a signal between
+setting up signal handlers and processing INIT, we would leak
+
+```
+$ ./example/hello -s -d -f mountpoint/
+[9/9] Linking target example/hello_ll
+FUSE library version: 3.14.1
+nullpath_ok: 0
+
+=================================================================
+==178330==ERROR: LeakSanitizer: detected memory leaks
+
+Direct leak of 352 byte(s) in 1 object(s) allocated from:
+    #0 0x7fbb19abf411 in __interceptor_calloc /usr/src/debug/gcc/gcc/libsanitizer/asan/asan_malloc_linux.cpp:77

+
+SUMMARY: AddressSanitizer: 352 byte(s) leaked in 1 allocation(s).
+```
+
+That's because `fuse_lowlevel.c`s `fuse_session_destroy` would only call
+the user supplied `op.destroy`, if INIT had been processed, but the high
+level API relied on `op.destroy` to free `f->fs`.
+
+This patch moves the freeing into `fuse_destroy` that will always be
+called by our high-level API.
