Hi Christoph,

thanks for the error report and sorry I didn't respond earlier.
The gm2 lists treats all emails from non subscribed posters as
spam and I didn't check the spam folder as regularly as I should!

The error is due to not patching gcc/ggc-page.c
it requires a patch which forces ggc_collect to return
immediately.


void
ggc_collect ()
{
  return;   /* add this line to gcc-3.2/gcc/ggc-page.c */


this will fix the above error..

Gaius
