Symptoms:
PHSS_37040:
JAGag44044: libunwind memory leak in _Unwind_Backtrace
PHSS_36352:
JAGag41939: Programs calling internal undocumented
routines in libunwind may abort or fail to load due to
unresolved "Unwind_Context" symbols, such as
_ZN15_Unwind_Context5setGREjm12_UNW_Boolean.
JAGag36095: Unwinder may restore NaT bits incorrectly
during C++ exception handling, possibly causing SIGILL.
JAGag39913: Throwing a C++ exception from a signal handler
results in an uncaught exception.
Defect Description:
PHSS_37040:
JAGag44044: _Unwind_Backtrace did not free all of the
temporary storage that it allocated.
PHSS_36352:
JAGag41939: Undocumented routines were not exported by
libunwind.
JAGag36095: The AR.RNAT register was not being restored
correctly during the stack unwind operation.
JAGag39913: The context was not being restored correctly
when unwinding through a signal handler during C++
exception processing.
Enhancement:
No (superseded patches contained enhancements)
PHSS_36352:
This patch delivers new interfaces to read and write
optimizer annotation information and C++ exception
handling tables, for use by third-party instrumentation
tools.
