I studied the gcc/ and libgcc/ code. I cannot make out why this is happening, though the debugging session does show this clearly. What I am trying to do with the patch is to show what was required to make things work; however, as you said it is not the fix for the core issue. About 2^32 times: yes if we had 2^32 files in any given project, it would definitely iterate that many times and fail. In what I saw with my debugging, the circular list contains as many elements as the number of source files in a project, and the loop iterates that many times. There could be a better way to iterate through a circular list, though. > > nathan > > -- > Nathan Sidwell
