Bash-3.1 Official patch 10
BASH PATCH REPORT

Bash-Release: 3.1
Patch-ID: bash31-010
Bug-Reported-by: [EMAIL PROTECTED]

Bug-Description:
There is a difference in behavior between bash-3.0 and bash-3.1 involving
parsing of single- and double-quoted strings occurring in old-style
command substitution. The difference has to do with how backslashes are
processed. This patch restores a measure of backwards compatibility while
the question of POSIX conformance and ultimately correct behavior is discussed.

This can cause a foreground process (including the foreground shell) to get read errors and exit.
