glGenTextures call results in "Bus error"

Hi,

I am writing an OpenGL/GLUT project in pure C, and I've come across a disturbing problem: calling glGenTextures results in the application crashing with "Bus error" being printed to the console. A crash log is also generated by CrashReporter.

In an attempt to isolate the true problem, I created a fresh Xcode project with one single .c file: it contains nothing but a main() entry point, and a simple call to glGenTextures. Unfortunately, the same exact issue persists even in this isolated environment.

I am writing and executing this code on a first-generation MacBook running OS X 10.5. The CPU is an Intel Core Duo, and the graphics processor is an integrated Intel GMA 950 chip.

Bizarrely, this same code runs without any problems on a Windows machine using the latest GLUT libs from Nate Robins' website.

Any help regarding this matter will be greatly appreciated. Below I have cited all relevant information to the problem. Thanks for reading!

Here is the complete code (gentextures.c):
-----------

#include <GLUT/glut.h>

int main(int argc, char *argv[])
{
	GLuint t;
	
	glGenTextures(1, &t);
	return 0;
}

And here is an excerpt from the crash report:
-----------
Exception Type:  EXC_BAD_ACCESS (SIGBUS)
Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000000
Crashed Thread:  0

Thread 0 Crashed: 0 libGL.dylib 0x95eb7ddb glGenTextures + 27 1 GenTextures 0x00001ff9 main + 31 (gentextures.c:9) 2 GenTextures 0x00001fae start + 54
