I think your code is correct. As far as I can tell, according to the standard an ELF file is supposed to be loaded using program headers and not section headers.

Can you please submit your new code as a patch against the current CVS tree?

Ummm... are you aware of the fact that you don't clear the BSS are, which is required by the standard?

Best regards,

Wolfgang Denk
