The problem is (seen on another report too): GCC hardened is compiling that code as PIE code (like PIC libraries), so it reserves EBX for usage of the GOT table (this is detailed in the SysV i386 ELF ABI docs). Actually, I know a way to fix it, it's a bit of an hack but should work. (I.e., using again a "g" constraint for that parameter and adding a mov %n, %%ebx there - but then I should add a clobber for ebx, and maybe GCC could still complain). -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
