I try it with gdb-cvs-head:
(top-gdb) disassemble /m main
Dump of assembler code for function main:
26 {
0x0808ce30 <main+0>: lea 0x4(%esp),%ecx
0x0808ce34 <main+4>: and $0xfffffff0,%esp
0x0808ce37 <main+7>: pushl -0x4(%ecx)
0x0808ce3a <main+10>: push %ebp
0x0808ce3b <main+11>: mov %esp,%ebp
0x0808ce3d <main+13>: push %ecx
0x0808ce3e <main+14>: sub $0x14,%esp
0x0808ce41 <main+17>: mov (%ecx),%eax
0x0808ce43 <main+19>: mov 0x4(%ecx),%edx
27 struct captured_main_args args;
28 memset (&args, 0, sizeof args);
0x0808ce46 <main+22>: lea -0x14(%ebp),%ecx
29 args.argc = argc;
0x0808ce57 <main+39>: mov %eax,-0x14(%ebp)
30 args.argv = argv;
0x0808ce5a <main+42>: mov %edx,-0x10(%ebp)
31 args.use_windows = 0;
0x0808ce49 <main+25>: movl $0x0,-0xc(%ebp)
32 args.interpreter_p = INTERP_CONSOLE;
0x0808ce50 <main+32>: movl $0x8299148,-0x8(%ebp)
33 return gdb_main (&args);
---Type <return> to continue, or q <return> to quit---
0x0808ce5d <main+45>: mov %ecx,(%esp)
0x0808ce60 <main+48>: call 0x808ce70 <gdb_main>
34 }
0x0808ce65 <main+53>: add $0x14,%esp
0x0808ce68 <main+56>: pop %ecx
0x0808ce69 <main+57>: pop %ebp
0x0808ce6a <main+58>: lea -0x4(%ecx),%esp
0x0808ce6d <main+61>: ret
End of assembler dump.
(top-gdb) quit
Everything is OK.
Thanks,
