AVR C Runtime Library - Bugs: Submit Item
Preamble
Please note that any followups will communicate through the email address registered with the savannah user profile. This will be used for any notifications with the bug tracker filed, including requests for further information that is required to resolve the issue.
Please indicate the avr-libc release number the bug is reported for. This can normally be found in the header file <avr/version.h>. Only very old versions (up to 1.2.x) did not have this header file.
Try making the bug as transparent to the developers as possible; a bug that isn't reproducible stands only a low chance of being fixed. Attach the file(s) that can be used to reproduce the bug (try stripping it down to the bare minimum that just demonstrates the bug, rather than submitting a full project archive or such), and/or other material that gives insight into the nature of the bug.
If there is a suggested fix, it can be attached as a patch, too (but please don't submit it inline in the text, the formatting will otherwise mangle it). Alternatively, it can be filed in a patch tracker item, which can be referred to as "patch #NNNN" in the text.
