State-Changed-Why:
    What is the assembly code you get when you compile this program (gcc -S ...)?  The one I get looks quite reasonable.

State-Changed-Why:
    The assembly code is perfectly reasonable. The problem might be in the assembler, as you said, or in the linker, or in glibc.  But GCC is doing its job perfectly, so I"m closing this GCC bug report.

GCC version:
Reading specs from /usr/local/gcc-3.0.1/lib/gcc-lib/i586-pc-linux-gnu/3.0.1/specs
Configured with: ../gcc-3.0.1/configure --with-gnu-ld --with-gnu-as --prefix=/usr/local/gcc-3.0.1
Thread model: single
gcc version 3.0.1


System environment:
i586-pc-linux-gnu


>Description:
Background:
I wondered, why several configure-scripts regarded gcc-3.0.1 as a cross compiler. The attached _simple_ program demonstrates that. It compiles without errors, but at runtime the program exits with a segmentation fault.
Somewhat strange...

Compiler output:

none

Preprocessor file:
see attachment

Options given at GCC compile-time:
Configured with: ../gcc-3.0.1/configure --with-gnu-ld --with-gnu-as --prefix=/usr/local/gcc-3.0.1
Built with: make bootstrap

>How-To-Repeat:
/usr/local/gcc-3.0.1/bin/gcc -o conftest conftest.c
