Package: openvrml-lookat Version: 0.14.3-3 Severity: normal File: /usr/bin/lookat
When I try to use lookat to display a VRML model available from onemap.org, it print a few messages, display a black window, and crashes when I press the right mousebutton in this window and try to select a viewpoint. This is the output: % lookat http://www.onemap.org/resources/sentrum/WorldSingleEG/world/DisplayTerrain.wrl system.cpp:159: Connecting to www.onemap.org ... system.cpp:169: connected. system.cpp:259: Read 6k from http://www.onemap.org/resources/sentrum/WorldSingleEG/world/DisplayTerrain.wrl free(): invalid pointer 0xbffff480! Unreachable URI. [ At this point I tried to select viewpoint with the mouse ] X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 12 (X_ConfigureWindow) Value in failed request: 0x0 Serial number of failed request: 2644 Current serial number in output stream: 2645 % I expected the window to be non-black, and the viewpoint switching to work. The free() message seem fatal to me. When I try to do the samme while using valgrind, it detects several errors: % valgrind lookat http://www.onemap.org/resources/sentrum/WorldSingleEG/world/DisplayTerrain.wrl ==4073== Memcheck, a memory error detector for x86-linux. ==4073== Copyright (C) 2002-2004, and GNU GPL'd, by Julian Seward et al. ==4073== Using valgrind-2.2.0, a program supervision framework for x86-linux. ==4073== Copyright (C) 2000-2004, and GNU GPL'd, by Julian Seward et al. ==4073== For more details, rerun with: -v ==4073== system.cpp:159: Connecting to www.onemap.org ... system.cpp:169: connected. system.cpp:259: Read 6k from http://www.onemap.org/resources/sentrum/WorldSingleEG/world/DisplayTerrain.wrl ==4073== Invalid read of size 1 ==4073== at 0x1B904788: strlen (mac_replace_strmem.c:189) ==4073== by 0x1BC72446: openvrml::doc2::filename(char*, unsigned) (in /usr/lib/libopenvrml.so.4.0.1) ==4073== by 0x1BC71DB6: openvrml::doc2::input_stream() (in /usr/lib/libopenvrml.so.4.0.1) ==4073== by 0x1BCC14BF: openvrml::scene::scene(openvrml::browser&, std::vector<std::string, std::allocator<std::string> > const&, openvrml::scene*) (in /usr/lib/libopenvrml.so.4.0.1) ==4073== Address 0x52BFE430 is just below %esp.
