 Why is it happening only there?

 It's /bin/sh, which is "GNU bash, version 3.2.17(1)-release (powerpc-
 apple-darwin9.0)." It works OK. The problem is with the files that build
 Guile. The set of executables involved in executing the right side of the
 pipe perform (minimised with `sort -u`):

 {{{
 +
 DYLD_LIBRARY_PATH=/opt/local/var/macports/build/.../guile/work/guile-2.2.2
 /guile-readline/.libs
 +
 DYLD_LIBRARY_PATH=/opt/local/var/macports/build/.../guile/work/guile-2.2.2/libguile/.libs:
 /opt/local/var/macports/build/.../guile/work/guile-2.2.2/guile-
 readline/.libs
 +
 DYLD_LIBRARY_PATH=/opt/local/var/macports/build/.../guile/work/guile-2.2.2/libguile/.libs:
 /opt/local/var/macports/build/.../guile/work/guile-2.2.2/libguile/.libs:
 /opt/local/var/macports/build/.../guile/work/guile-2.2.2/guile-
 readline/.libs
 +
 LTDL_LIBRARY_PATH=/opt/local/var/macports/build/.../guile/work/guile-2.2.2/libguile:
 /opt/local/var/macports/build/.../guile/work/guile-2.2.2/guile-readline
 +
 LTDL_LIBRARY_PATH=/opt/local/var/macports/build/.../guile/work/guile-2.2.2
 /guile-readline
 }}}

 Only *one* directory with *one* `dylib` exists:
 `/opt/local/var/macports/build/.../guile/work/guile-2.2.2/libguile/.libs`.
 So the last assignments seem wrong. Anyway, `gbd` explains:

 {{{
 gdb -arch ppc --core=/cores/core.27026
 GNU gdb 6.3.50-20050815 (Apple version gdb-967) (Tue Jul 14 02:15:14 UTC
 2009)
 ...
 This GDB was configured as "powerpc-apple-darwin".
 Core was generated by
 `/opt/local/var/macports/build/_opt_local_var_macports_sources_nue.de.rsync.macports.org_macports_release_tarballs_ports_lang_guile/guile/work/guile-2.2.2/libguile/.libs/guile'.
 }}}

 So it's neither cat nor bash nor the OS but the recently built guile
 binary that crashes and produces the ¼ GB big core files.
