+Subject: [PATCH] bpf-translate.cxx: fix build against upcoming `gcc-14`
+ (`-Werror=calloc-transposed-args`)
+
+`gcc-14` added a new `-Wcalloc-transposed-args` warning recently. It
+detected minor infelicity in `calloc()` API usage in `systemtap`:
+
+    bpf-translate.cxx: In function 'bpf::BPF_Section* bpf::output_probe(BPF_Output&, program&, const std::string&, unsigned int)':
+    bpf-translate.cxx:5044:39: error: 'void* calloc(size_t, size_t)' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
+     5044 |   bpf_insn *buf = (bpf_insn*) calloc (sizeof(bpf_insn), ninsns);
+          |                                       ^~~~~~~~~~~~~~~~
+    bpf-translate.cxx:5044:39: note: earlier argument should specify number of elements, later size of each element
+
+Upstream-Status: Backport [https://sourceware.org/git/?p=systemtap.git;a=commit;h=d42139cf9cd26d0c0363fcfe007716baeb8de517]
