The question I asked is why doesn't this happen for 'const'? That turned out to be a good question, because it leads to the better question of what debugging output did you expect for this code, anyway? It seems to me that __noalias__ is an interesting attribute that should be somehow reflected in the DWARF. That would require a GNU extension, of course. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28834

--- Comment #10 from dpatel at apple dot com 2006-08-30 07:47 --- Pinski, Please do not reinsert my email address in CC list, again (and learn to not jump to conclusion based on biased views) May be it is not a good idea to ask dwarf generator to handle a case where two shallow copy of same struct refers same field ? May be equate_decl_number_to_die() should handle it properly ? May be it is appropriate to have one field be a member of multiple structures ? -- dpatel at apple dot com changed: What|Removed |Added CC|dpatel at apple dot com | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28834

--- Comment #9 from pinskia at gcc dot gnu dot org 2006-08-30 03:28 --- Devang, Why did you remove your self, you caused this regression. Yes you might not work on GCC any more for Apple but that does not take you away from fixing the regression you caused. I am a bit upset at this behavior of going away and not going to fix a regression you caused. -- Pinski [EMAIL PROTECTED]2006-08-29 17:46:15 CC [EMAIL PROTECTED] -- pinskia at gcc dot gnu dot org changed: What|Removed |Added CC||dpatel at apple dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28834

--- Comment #8 from geoffk at gcc dot gnu dot org 2006-08-29 04:48 --- In the duplicate I explain: The problem is that the front-end is calling the DWARF output code with two shallow copies of the same structure, 'S'. The DWARF code detects that two different structures have the same members and aborts. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28834
