Package: nodejs
Version: 12.20.2~dfsg-2
Severity: serious
Justification: segfaults
File: /usr/bin/node
Hi maintainer,
As can be seen in the autopkgtest history of node-opencv [1], that
autopkgtest regularly fails, and all failures with logs still present
are due to the same issue: node segfaults. The output from one of these
logs is at the bottom of this mail.
I ran the lines from d/t/unittest manually upto the last call and next I
ran $(node readimage.js) twice. The second time already triggered the
issue, see below.

Please let me know if you need more info or if I can you more useful
info (step by step please, I have no clue how node works).
