vx32_getcontext return throws vxtrap 14

Hi Team,

I'm trying to get the code running on a recent linux version
Linux dev-box 4.4.0-116-generic #140-Ubuntu SMP Mon Feb 12 21:23:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

and whatever code I run through vxlinux always generated a trap error 14 after calling vx32_getcontext.

Any idea on how to solve this ?

Thx a lot
