It's a standard C assert; and the way to avoid these is to define NDEBUG
(i.e., add "-DNDEBUG" to CPPFLAGS when configuring).

But please send me the problem file. It's a bug that this assertion is
failing.

Such files are not conforming. I am unlikely to add a mechanism to
OpenVRML to suppress them. However, openvrml::browser uses a
user-suppled std::ostream for its console output. You could supply an
ostream that filters these out.
