[PURRS-devel] Re: CLN 1.1.4 and GCC 3.1

[Richard B. Kreckel]

Hi there,

I should have looked closer at your bugreport when you first submitted it.  
This is indeed a bug in the assembler 'gas', so in the binutils package,
that was triggered by CLN and fixed by Bruno Haible a couple of weeks ago.

It seems like binutils-2.12.1 does not fix the problem yet.  Hence, you
have three options:
1) Downgrade binutils to a version that has worked before
2) Wait for a new version of binutils.
3) Manually apply the following patch to gas/dwarf2dbg.c that was applied
   upstream by Nick Clifton <nickc at cambridge.redhat.com> on May 11 and
   build and install your own binutils:
