  <description>
This update for bash fixes an issue that could lead to syntax errors when parsing
scripts that use expr(1) inside loops.

Additionally, the popd build-in now ensures that the normalized stack offset is
within bounds before trying to free that stack entry. This fixes a segmentation
fault.
