I'm not able to reproduce this problem.  The test runs fine on my system
with 58 expected passes and no failures.  Could it be related to the tcl
version?

As a rough guess, could you try the patch below to initialize the array
variable?

diff --git a/gdb/testsuite/gdb.multi/multi-kill.exp b/gdb/testsuite/gdb.multi/multi-kill.exp

 for {set i 1} {$i <= $NUM_INFS} {incr i} {
     if {[start_inferior $i] < 0} {
