Description

The `make check' target of the Makefile fails to build on x86, AMD64 is fine. Output is (stripped to relevant parts only):

or

/bin/bash: line 5: 29956 Segmentation fault      ${dir}$tst

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 ./.libs/test_freelist run shows:

Core was generated by `./.libs/test_freelist'.

I'm not familiar with ATS' data structures, but gdb indicates the following values:

$2 = {s = {pointer = 0x1f1f1f1f, version = 165962584}, data = 712803871161786143}
(gdb) print f
$3 = (InkFreeList *) 0x94ff018
(gdb) print f->offset
$4 = 0
