+Subject: [PATCH] Fix use-after-free warning
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When building, I get the following warning:
+
+```bash
+$ ninja
+[18/71] Compiling C object lib/libfuse3.so.3.14.1.p/modules_iconv.c.o
+../lib/modules/iconv.c: In function ‘iconv_convpath’:
+../lib/modules/iconv.c:85:38: warning: pointer ‘newpath’ may be used after ‘realloc’ [-Wuse-after-free]
+   85 |                         p = tmp + (p - newpath);
+      |                                   ~~~^~~~~~~~~~
+../lib/modules/iconv.c:80:31: note: call to ‘realloc’ here
+   80 |                         tmp = realloc(newpath, newpathlen + 1);
+      |                               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+[71/71] Linking target example/passthrough_hp
+```
+
+It's a false positive,  I thinks.  But it's also easy to silence this
+warning with a small refactor.
