4.47. gawk

An updated gawk package that fixes a bug is now available for Red Hat Enterprise Linux 5.
The gawk package contains the GNU version of awk, a text processing utility. Awk interprets a special-purpose programming language to do quick and easy text pattern matching and reformatting jobs.

Bug Fix

BZ#629196
Prior to this update gawk interpreted (under certain circumstances) some run-time variables as internal zero-length variable prototypes. When gawk tried to free such run-time variables, it actually freed the internal prototypes, that were allocated just once due to memory savings. Consequently gawk sometimes failed and the error message "awk: double free or corruption" was displayed. With this update the problem has been corrected and the error no longer occurs.
All users of gawk are advised to upgrade to this updated package, which fixes this bug.
