Hi! ----
32bit ast-ksh.2009-05-05 _may_ crash on Solaris 11 SPARC+x86 when running fftw-2.1.5 "configure". The problem is a bit difficult to reproduce since it only occurs around ~30% of the "configure" runs, only happens for 32bit binaries and only if "configure" exclusively uses ksh93 (this happens on OpenSolaris/Indiana where /sbin/sh+/bin/sh+/usr/bin/sh is ksh93). Steps to reproduce: 1. Install _32bit_ ast-ksh.2009-05-05 as /home/test001/bin/ksh $ wget 'http://src.opensolaris.org/source/raw/sfw/usr/src/lib/fftw2/fftw-2.1.5.tar.gz' 2. Run the following build sequence: -- snip -- ( gzcat <fftw-2.1.5.tar.gz | tar -xf - ; cd fftw-2.1.5 ; cat configure | sed 's/\/bin\/sh/\/home\/test001\/bin\/ksh/g' >configure_mod ; (LC_ALL=C SHELL=/home/test001/bin/ksh CONFIG_SHELL=/home/test001/bin/ksh VMDEBUG=a /home/test001/bin/ksh configure_mod --no-reexec --prefix=/usr --enable-threads --enable-shared --disable-static) 2>&1 | tee buildlog.log) -- snip -- "configure_mod" then crashes like this: -- snip -- checking for a BSD-compatible install... /usr/bin/ginstall -c checking whether build environment is sane... yes checking for gawk... gawk checking whether make sets $(MAKE)... yes checking type prefix for installed files...
