--- Comment #13 from eric dot weddington at atmel dot com 2010-08-22 13:26 --- (In reply to comment #12) See http://www.avrfreaks.net/index.php?name=PNphpBB2file=viewtopicp=736616 This is (IMO) a bug in the __do_global_ctors in gcc/config/avr/libgcc.S When support for 24-bit flash pointers was added in edit http://gcc.gnu.org/viewcvs?view=revisionrevision=143306 R20 was used to hold the extra 8 bits of address. But R20 is NOT preserved by called functions according to the AVR C calling conventions, and indeed the class initialization code ends up using R20 if there are sufficient fields to initialize. The attached patch uses R15 instead, and appears to work, but I'm not sure of the implications... I tried to change the summary, but of course it won't let me. I think this is a more serious problem than the initial problem indicates... Duplicate of bug #45263. Closing this one as a dup, as the test case in bug #45263 is simpler. *** This bug has been marked as a duplicate of 45263 *** -- eric dot weddington at atmel dot com changed: What|Removed |Added CC||eric dot weddington at atmel ||dot com Status|WAITING |RESOLVED Resolution||DUPLICATE http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44617

The test contains these declarations:

An int on the AVR is 16-bits, hence the width of 'a' and 'b' exceed their type.

--- Comment #3 from eric dot weddington at atmel dot com 2008-10-30 19:57 --- (In reply to comment #2) I don't know how to compile/test AVR. Is it in the CompileFarm? To anyone with more knowledge on AVR, any suggestion what could cause this? Is there any special about signed/unsigned multiplication on AVR? I don't know if it is in the Compile Farm, or not. But I can test for you. Note that AVR has 8-bit chars, 16-bit ints and pointers, 32-bit longs. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37960
