Package: gcc-4.0 Version: 4.0.1-2 Severity: important Hi,
Description: I am running a program that is outputing a file. The very same program when run with LD_PRELOAD set to libGL.so, is segfaulting. The segfault does not occur when using gcc2.95, gcc3.2, gcc3.3 and gcc3.4 (debian package). The segfault also does not occur when 'unset'ing the env var LD_PRELOAD. The backtrace can be found here: http://www.creatis.insa-lyon.fr/~malaterre/gcc/gdb.log And I ran also strace with/ and without LD_PRELOAD set: $ export LD_PRELOAD=/usr/X11R6/lib/libGL.so $ strace /home/mathieu/Dashboards/MyTests/VTK-gcc4/bin/vtkParseOGLExt /home/mathieu/Dashboards/MyTests/VTK-gcc4/Rendering /home/mathieu/Dashboards/MyTests/ParaView/VTK/Utilities/ParseOGLExt/headers/glext.h /home/mathieu/Dashboards/MyTests/ParaView/VTK/Utilities/ParseOGLExt/headers/glxext.h /home/mathieu/Dashboards/MyTests/ParaView/VTK/Utilities/ParseOGLExt/headers/wglext.h >& /tmp/log1 $ unset LD_PRELOAD $ strace /home/mathieu/Dashboards/MyTests/VTK-gcc4/bin/vtkParseOGLExt /home/mathieu/Dashboards/MyTests/VTK-gcc4/Rendering /home/mathieu/Dashboards/MyTests/ParaView/VTK/Utilities/ParseOGLExt/headers/glext.h /home/mathieu/Dashboards/MyTests/ParaView/VTK/Utilities/ParseOGLExt/headers/glxext.h /home/mathieu/Dashboards/MyTests/ParaView/VTK/Utilities/ParseOGLExt/headers/wglext.h >& /tmp/log2 Those logs files can be found here: http://www.creatis.insa-lyon.fr/~malaterre/gcc/log1 and http://www.creatis.insa-lyon.fr/~malaterre/gcc/log2 ----------------------------------------------------------------------------------- Anyone interested in reproducing the bug need a debian testing with gcc4: (assuming gcc points to gcc 4.0.1) $ sudo apt-get install cmake $ cvs -d:pserver:[EMAIL PROTECTED]:2401/cvsroot/VTK login $ cvs -d:pserver:[EMAIL PROTECTED]:2401/cvsroot/VTK co VTK $ mkdir VTK-gcc $ cd VTK-gcc $ cmake ../VTK $ make ... It should take a while to compile, but when entering in VTK-gcc/Rendering the segfault should occur.
