Package: python-opengl Version: 3.0.0~b1-2 Severity: normal
When the default python version in testing changed to 2.5 I found a program I had written failed with segmentation faults. I've narrowed down the bug. The following is the smallest reasonable piece of code which will cause the segfault: from OpenGL.GLUT import * glutInit(["appname"]) glutInitDisplayMode(GLUT_RGB) glutInitWindowSize(640, 480); glutCreateWindow("appname") def disFunc(): print "disFunc" def keyFunc(*args): print "keyFunc" glutDisplayFunc(disFunc) glutKeyboardFunc(keyFunc) glutMainLoop() Pasting the code into python interactive mode demonstrates the problem as well as using a .py file. Python will segfault as soon as it enters the glutMainLoop function. If either glutDisplayFunc(disFunc) or glutKeyboardFunc(keyFunc) is commented out, there is no problem, and things behave as you would expect them to. Also if I use python2.4, there is no problem. But if I use both keyFunc and disFunc in python2.5: SIGSEGV, every time. I'm not sure if a gdb backtrace is useful, but here it is, anyway: #0 0x00002aaaabac5fcc in ?? () #1 0x00002aaaab314e83 in ??
