i think that this is exactly the problem. i noticed already a few
months ago that the arguments that are used when calling the strncmp()
functions in THtml are not checked against a NULL pointer. the
implementation of the strncmp() function seems to be different on the
different platforms. some of them check the arguments against NULL and
others don't. the GNU C lib doesn't check, so it affects your IRIX 6.2/gcc
and my Linux system. so for instance the htmlFile variable in
THtml::MakeClass() should be protected agains NULL.

patrick.
