1.126.  libunwind

C++ programs which used standard C++ exceptions and were linked with the libunwind library could crash, due to a conflict between the unwinding capabilities contained in GCC and those provided by libunwind. libunwind used an outdated Application Binary Interface (ABI) which did not provide the GetIPInfo() function. When the libunwind unwinder was preferred over the GCC unwinder, then the missing GetIPInfo() function (which was provided by the GCC unwinder) was used together with libunwind's unwinding support. Because GCC's GetIPInfo() function must access the (valid) state of the GCC unwinder, an application crash could result. Because of this ABI change, libunwind required a small extension to its ABI to update it to the current unwinding ABI. This updated package provides that extension, thus removing the possibility for unwinding conflict and potential application crash. (BZ#480412)
