Address 0x7f9ffdca2050 is located in stack of thread T0 at offset 80 in frame
#0 0x564af456fc26 in cpumask_to_cpulist util/util.c:267
This frame has 2 object(s):
[32, 49) 'blk' (line 291)
[96, 1120) 'cpus' (line 271) <== Memory access at offset 80 underflows this variable
HINT: this may be a false positive if your program uses some custom stack unwind mechanism, swapcontext or vfork
(longjmp and C++ exceptions *are* supported)
