Public bug reported:

I am developing a custom program which used to work without errors in
Ubuntu 16.04, but crashes very often in the current release. The core
dump says the segmentation fault occurs in "__strcmp_ssse3", which is
ultimately called from OpenCV's VideoCapture constructor I use several
times in my program.

I attached an archive with the debug binary and the core dump to this
report (the password is the name of the function in which the bug
occurs).
