malloc error when compiling insn-attrtab.c

[Jens Bauer <jens@xxxxxxxxx>]

Hi,

I'm having so much trouble compiling gcc-4.6.x (4.6.1, 4.6.2, 4.6.3).

A malloc error occurs when I try to compile 'insn-attrtab.c'.

Here's the last output from my build.

My computer is a PowerMac G5, I'm running Mac OS X 10.5.8; I have nothing 'newer', so I can't try it on an intel based machine.
I use gcc-4.2 (which does _not_ work the same as gcc-4.2 on intel, so it might work fine on intel, even though it fails on PowerPC).

I can compile gcc 4.3.x up to 4.5.x (all inclusive), but 4.6.x is giving me trouble.
Does anyone know how to get me going ?


Love,
Jens
