Hello and best wishes,
[1 added current@ for a wider audience]
[2 the good news, I could install and run quite a number of
'portaghes' in the gentoo_stage3 chroot and this for
now is the only problem I have]

Some more info :
- it is not specific to just gconv_simple.c; Expat.c generated in
the XML-Parser portage has the same behaviour
- it is not specific to linux-gcc : it now hangs in
"bison -y -d -v 2>/dev/null ./parser.y"
a "ps axlww | fgrep 3758" shows :
0 37586 35141 0 76 0 2576 2300 ppwait D+ 0 0:00.04 make (gmake)

-current is as of Sat Dec 27
Thank you for any help
