Subject: bug#12031: Guile 2.0.6 build failure (segfault in test-with-guile-module, etc.)

There seems to be a problem on armhf (and perhaps also armel).  This is
with Guile 2.0.6 linked against Debian libgc-dev 7.1-9.

Builds fail like this:

  PASS: test-extensions
  /bin/bash: line 5: 14132 Segmentation fault      srcdir="." builddir="." CHARSETALIASDIR="/home/rlb/guile/guile-2.0.6/lib" GUILE_AUTO_COMPILE=0 "../../meta/uninstalled-env" ${dir}$tst
  FAIL: test-with-guile-module
  PASS: test-scm-with-guile
  /bin/bash: line 5: 14195 Segmentation fault      srcdir="." builddir="." CHARSETALIASDIR="/home/rlb/guile/guile-2.0.6/lib" GUILE_AUTO_COMPILE=0 "../../meta/uninstalled-env" ${dir}$tst
  FAIL: test-scm-spawn-thread
  /bin/bash: line 5: 14228 Segmentation fault      srcdir="." builddir="." CHARSETALIASDIR="/home/rlb/guile/guile-2.0.6/lib" GUILE_AUTO_COMPILE=0 "../../meta/uninstalled-env" ${dir}$tst
  FAIL: test-pthread-create

And here's the gdb stacktrace:

Please let me know if I can provide further information.
