julia fails to build with a segfault

[cmey]

Hi,
I'm trying to compile a fresh "git clone" of julia and it fails with a segfault on one of my 2 machines, on the other one it's OK.

[matlab@k52bgh86 julia_git]$ make
    JULIA usr/lib/julia/sys0.ji
Warning: New definition write/bin/sh: line 1:  5630 Erreur de segmentation  /home/matlab/cmey/julia_git/usr/bin/julia-release-readline -b stage0.jl

    long-needed update to type names in julia-mode

I also tried with Make.inc modified to USE_SYSTEM_READLINE=1 before make, with exactly the same segfault.

The precompiled 64-bit julia binary works.

[JeffBezanson]

GCC version 4.1.2 is known to have problems compiling our code. If you can upgrade gcc it might fix this.

[cmey]

Exact, switching to gcc 4.3.4 solved the problem.
Thank you :-)

@JeffBezanson do you think we should add a check for the gcc version to the Makefile and return a fatal error if the gcc version is not supported?
