Your bug reports play an essential role in making ld reliable.
Reporting a bug may help you by bringing a solution to your problem, or it may not. But in any case the principal function of a bug report is to help the entire community by making the next version of ld work better. Bug reports are your contribution to the maintenance of ld.
In order for a bug report to serve its purpose, you must include the information that enables us to fix the bug.
If you are not sure whether you have found a bug, here are some guidelines:
If the linker gets a fatal signal, for any input whatever, that is a ld bug. Reliable linkers never crash.
If ld produces an error message for valid input, that is a bug.
If ld does not produce an error message for invalid input, that may be a bug. In the general case, the linker can not verify that object files are correct.
If you are an experienced user of linkers, your suggestions for improvement of ld are welcome in any case.
