gcc-4.2 cannot compile bind 9.5.0.P2 on i386

Binary package hint: gcc-4.2

On i386 (amd64 is fine) bind9 9.5.0.P2 (and higher) stops with:

/bin/bash /tmp/buildd/bind9-9.5.0.dfsg.P2/libtool --mode=compile gcc -I/tmp/buildd/bind9-9.5.0.dfsg.P2 -I. -Iinclude -I/tmp/buildd/bind9-9.5.0.dfsg.P2/lib/dns/include -I../../lib/dns/include -I/tmp/buildd/bind9-9.5.0.dfsg.P2/lib/isc/include -I../../lib/isc -I../../lib/isc/include -I../../lib/isc/unix/include -I../../lib/isc/pthreads/include -I../../lib/isc/x86_32/include -I/usr/include -D_REENTRANT -DUSE_MD5 -DOPENSSL -DGSSAPI -DUSE_ISC_SPNEGO -fno-strict-aliasing -O2 -I/usr/include/libxml2 -W -Wall -Wmissing-prototypes -Wcast-qual -Wwrite-strings -Wformat -Wpointer-arith -fno-strict-aliasing -c stats.c

Strange thing is that x86_64 and x86_32 share same configuration (lib/isc/x86_32/include/isc/atomic.h) on platforms where gcc is available (configure.in overrides platform in this case) and x86_64 compiles just fine.

I also have checked diff between P1 and P2 (P1 compiled fine some time ago) and I didn't discovered any changes which should affect this.

I am trying this in clean pbuilder environment (hardy, hardy-security and hardy-updates enabled).
