I'm new to FASM, so I wonder why does this occur to me:
It looks like the program doesn't start at the 'start' label, but rather at the 'test_data'
even with 'entry start'. It always results in a "Segmentation fault". I tried moving the
data section after the start label and it worked, but isn't it supposed to work the original way ?

Code:
format ELF executable
entry start

section readable writeable
test_data dd 232,1245,121

section readable executable
start:
 ;...
 ;...

This is perhaps because of this: http://board.flatassembler.net/topic.php?t=3689
The last section of executable needs to be writeable.

Tomasz, can you add this issue to the "2.4.4 Executable and Linkable Format" section? I think all the people will think that this is a FASM's bug.

Regards,
Hernán

Well, the ELF format is more than just Linux thing.

I made that thread sticky; maybe we should go on with reporting this to developers, at least start some serious discussion on some kernel groups, whether violating the ELF specification is really a wise thing to do.
