1.149.1. RHBA-2010:0823: bug fix update
An updated tcsh package that fixes a bugs is now available.
Tcsh is an enhanced and compatible version of the C shell (csh). It is a command language interpreter, which can be used as an interactive login shell, as well as a shell script command processor.
This updated tcsh package fixes the following bugs:
* Previously, under certain circumstances, a null pointer may have been incorrectly dereferenced, causing the tcsh shell to terminate unexpectedly. With this update, the pointer is now checked properly and tcsh no longer crashes. (#631815)
* Previously, when command substitution with backquotes was used, extra fork() was performed. With this update, only one fork() is performed. (#640251)
* Previously, if printexitvalue was set, tcsh returns the exit code as part of the command output, rendering the output unusable. With this update, output of command is correct. (#640252)
All users of tcsh are advised to upgrade to this updated package, which resolves these issues.
