[avr-gcc-list] Problem with Library building with latest CVS GCC

[Francois Lorrain]

 Hello,

 I am trying to build the latest AVR - GCC / Binutils / AVR lib from the
CVS repositories.

 I know this is work in progress but I keep running into the same issue
...

Configure / make / make install for binutils : no problem
Configure / make  : fails with the following error :

 The error happens when GCC is trying to build the library for the AVR,
the as program just core dumps ...

  a little gdb session (below) shows that the error happens in line 1813
in config.c (gas/symbols.c)

 I am stuck here, anybody got an idea ?

 Here is the gcc command (with -v -save-temp parameters added)
