RHBA-2004:561 - Bug Fix Advisory

Topic

Updated gdb and libunwind (Itanium) packages that fix various bugs are now
available.

Description

GDB is a debugger for C, C++, and other programming languages. Libunwind
provides a C ABI to determine the call-chain of a program.

This updated gdb package is based on a snapshot from the Free Software
Foundation mainline, taken on June 7, 2004. It includes all the fixes that
are present in the FSF gdb-6.1.1 release. It also includes most patches
committed to mainline FSF up to Oct-04.

As a result of GDB motivated fixes in the kernel, signal handling is vastly
improved on all architectures and support for large corefiles is now fixed.

Multi-threaded watchpoint support has been added to x86, AMD64, Itanium,
and IBM eServer zSeries (partial).

This package fixes a problem with corrupted pc of threads on i386. This
package fixes a problem with GDB running wild with zero pc on Itanium.

All users of gdb or linunwind (Itanium) should upgrade to these updated
packages, which resolve these issues.
