If your backtrace is to be trusted, your stack is corrupted: > #0 0x00007ffff3bce8c9 in clib_memcpy_fast (dst=0x1881349000d2f00, > src=0x13010b390b3b0b, n=4182438362655424791)
Pointers and size look definitely wrong here. If the crash always happen at the same place, I'd recommend to break right before it and step-by-step to try to figure what is going on. ben > -----Original Message----- > From: vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> On Behalf Of chetan bhasin > Sent: mardi 25 mai 2021 09:21 > To: vpp-dev <vpp-dev@lists.fd.io> > Subject: [vpp-dev] Facing Abort in VPP with Sanitizer > > Hello Everyone, > > > We have back-merged ASAN related changes to vpp_1908 .
