or it even succeeds. This might be a race condition therefore. A backtrace from
a core dump of a crashed {{LD_PRELOAD=./.libs/libtsutil.so.2

I'm not familiar with ATS' data structures, but gdb indicates the following
values:
{code}
$2 = {s = {pointer = 0x1f1f1f1f, version = 165962584}, data =
712803871161786143}
(gdb) print f
$3 = (InkFreeList *) 0x94ff018
(gdb) print f->offset
$4 = 0
