Execution error with core dump: subversion 1.6.9

Hello,

our system programmers installed a new version of AIX 6.1. After the typical
configure/make/make install I can't execute svn without generating a core
dump.

In the attachment I send you the result file test.log (make check)

This is my building configuration:

APR="${PRG}/apache/current"
EXPAT="${PRG}/expat/current"

CFLAGS="-I${EXPAT}/include ${CFLAGS}"
CPPFLAGS="-I${EXPAT}/include ${CPPFLAGS}"
LDFLAGS="-L${EXPAT}/lib ${LDFLAGS}"
export CFLAGS CPPFLAGS LDFLAGS

OBJECT_MODE=64 CFLAGS="${CFLAGS}" CPPFLAGS="${CPPFLAGS}" LDFLAGS="${LDFLAGS}"
\
  CC="xlc_r -q64" CXX="xlC_r -q64" AR="ar -Xany" RANLIB="ranlib -X32_64" \
  ./configure \
  --prefix=${PFXDIR} \
  --with-apr=${APR} \
  --with-apr-util=${APR} \
  --with-apxs=${APR}/bin/apxs \
  --disable-mod-activation \
  --without-serf \
  --without-neon \
  --without-berkeley-db \
  --disable-nls \
  --disable-neon-version-check \
  --enable-debug \
  --enable-shared=no \
   2>&1 | tee /tmp/x

The debug shows following message:

mue_at_mwtest> dbx svn
Type 'help' for help.

Yours sincerly
