[bug-recutils] [BUG] recutils 1.8, editing error if TMPDIR is on a tmpfs

[Juergen Daubert]

Hello,

first thanks for the new release, nice to see that recutils is still
maintained.

I have the following issue:

my /tmp directory is on a tmpfs, mounted with

$:> mount | grep /tmp
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,relatime,size=20971520k)

if I try to edit a recutil file

$:> touch test.rec
$:> recins -r "Name: Test" test.rec
recins: error: renaming file /tmp/receVREcm to test.rec

and the relevant part of a strace with the above command

access("test.rec", W_OK)                = 0
stat("test.rec", {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
stat("/tmp", {st_mode=S_IFDIR|S_ISVTX|0777, st_size=320, ...}) = 0
getpid()                                = 566
openat(AT_FDCWD, "/tmp/recDHlD7C", O_RDWR|O_CREAT|O_EXCL, 0600) = 4
fcntl(4, F_GETFL)                       = 0x8002 (flags O_RDWR|O_LARGEFILE)
fstat(4, {st_mode=S_IFREG|0600, st_size=0, ...}) = 0
write(4, "Name: Test\n", 11)            = 11
close(4)                                = 0
rename("/tmp/recDHlD7C", "test.rec")    = -1 EXDEV (Invalid cross-device link)

write(2, "recins", 6recins)                   = 6
write(2, ": error: ", 9: error: )                = 9
write(2, "renaming file /tmp/recDHlD7C to "..., 41renaming file /tmp/recDHlD7C

I'm using an up-to-date CRUX distro with gcc 7.4.0 and glibc 2.27.

best regards
