Frank,

a couple of remarks:
- there are memory leaks in the code (moduleDir can be leaked, as well 
as the newly found pathname)
- for the code to still be readable, I'd rather but in a single function 
all the processing required, ie. do it the same way as for the other 
debug information: if the .gnu_debuglink section is found, map it, and 
then let this new function handle the lot

A+
