[Exim] Bug in Exim 4.41: "Cannot lock: Invalid Argument"

Hi,

after upgrading from Exim 4.10 to 4.41 every incoming mail produces
the following output:

2004-08-01 14:37:03 1BrFaI-0001y0-PD Cannot lock /var/spool/exim/input//1BrFaI-0001y0-PD-D (22): Invalid argument

strace shows:

[pid  7540] open("/var/spool/exim/input//1BrFaI-0001y0-PD-D", O_RDWR|O_CREAT|O_EXCL|O_LARGEFILE, 0640) = 1
[pid  7540] fchown(1, 8, 12)            = 0
[pid  7540] fchmod(1, 0640)             = 0
[pid  7540] fcntl(1, F_GETFL)           = 0x8002 (flags O_RDWR|O_LARGEFILE)
[pid  7540] fstat(1, {st_mode=S_IFREG|0640, st_size=0, ...}) = 0
[pid  7540] old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40019000
[pid  7540] _llseek(1, 0, [0], SEEK_CUR) = 0
[pid  7540] fcntl(1, 0xd /* F_??? */, 0xbfffee90) = -1 EINVAL (Invalid argument)

permissions are correct and empty spool files are created.

System: Redhat 7.0, glibc 2.1.92, gcc version 2.96 20000731 (Red Hat Linux 7.0)

I had to downgrade to 4.10 to get it working again.
