+linux-user elf loader issue
+
+all versions up to 4.0 (I didn't test others)
+file affected linux-user/elfload.c
+function load_elf_image
+
+if (phdr[i].p_type == PT_LOAD) {
+           
+-            abi_ulong a = phdr[i].p_vaddr - phdr[i].p_offset; 
++            abi_ulong a = phdr[i].p_vaddr ; // - phdr[i].p_offset; 
+            if (a < loaddr) {
+                loaddr = a;
+
+To the best of my understanding of the elf format p_offset is not a virtual offset. In fact, when I load statically compiled applications, the load fails because the libc before main is trying to access phdr in the executable image but that memory is not mapped -- this is caused by the wrong loaddr above.
+
+Have you got a test case? The check-tcg tests all pass and they are statically linked elfs.
