This frame has 3 object(s):
[48, 50) 'queue_id' (line 374) <== Memory access at offset 48 partially
overflows this variable
[64, 72) 'deq_buffers' (line 376)
[96, 104) 'buffers' (line 375)
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)
