More or less. What's clear is that the three-section (begin, content, end)
trick is not very reliable on Mac OS X because of the linker, and it doesn't
appear consistent across different OS versions (this bug seem to be 10.5.x
only). The solution that is expected to work is to replace the three-section
trick with something more reliable.
It's true that the discussion has extended to support of dynamic libraries.
That's mainly because loading a library involves the same process about finding
the address and size for different segments in the library, and the solution
was inspired from code meant to work with dynamic libraries.
If all we wanted was to fix this bug, probably calling this function to get the
address and size of a section instead of the current method would be enough:
char* getsectdata(
const char* segname,
const char* sectname,
unsigned long* size);
It won't work with dynamic libraries, but I'd expect the hello world crash on
10.5.x to disappear.
