Bug #220867 concerns various programs putting out the following error message:
ld.so: Incorrectly built binary which accesses errno or h_errno directly. ld.so: See /usr/share/doc/libc6/FAQ.gz. You closed the bug with the following comment: The application should continue to run for now, but when the warning message is printed use of the NPTL threading library, and other new kernel-2.6 features, are disabled. I don't necessarily wish to reopen the bug but I would like to point out the scenario I just encountered. I use qmail, which uses the pop3d pop3 server. pop3d calls a program called checkpassword to verify the user's password. When I updated my server today, checkpassword started printing the error message above. pop3d returned the error message and THEN the +OK message indicating a successful login to my email client (Evolution.) Evolution, seeing the ld.so error message, believed the login was unsuccessful and halted the attempt to download my mail. Thus, checkpassword did continue to function along with printing out the error message, but the error message itself interfered with the communications between my MUA and the pop3 server. Bottom line - I was unable to check my email. I was able to patch the source of checkpassword by grepping for the "extern int errno", which appeared in a file called errno.h, and replacing it with an #include directive for errno.h, then recompile and correct the problem. As I said, I don't necessarily want to reopen the bug but I did want to point out that, in some circumstances, at least, the problem causes more than just spurious error messages.
