[libunwind] My test pgm works but Oracle does not!

[Rohini J.P]

Hi,

I wanted to debug a setjmp problem in Oracle code and hence installed
my own version debuggable of libunwind library on my Itanium Linux
system. The version I installed is

libunwind-ia64.so        libunwind-setjmp.la  libunwind.la
libunwind-generic.a   libunwind-ia64.so.7      libunwind-setjmp.so
libunwind.so libunwind-generic.so  libunwind-ia64.so.7.0.0
libunwind-setjmp.so.0   libunwind.so.7 libunwind-ia64.a
libunwind-ptrace.a libunwind-setjmp.so.0.0.0  libunwind.so.7.0.0
libunwind-ia64.la     libunwind-setjmp.a       libunwind.a

A small test program that uses setjmp works with my new libunwind
library and I am able to step through the libunwind code. But when I
used the same library for the Oracle code I am debugging, Oracle code
core dumps at various places. I want to know what could be the
problem.

The libunwind library present on my system is as follows.

/usr/lib/libunwind-generic.a   /usr/lib/libunwind-ia64.so.1.2.0
/usr/lib/libunwind-setjmp.so.0.0.0
/usr/lib/libunwind-generic.so  /usr/lib/libunwind-ptrace.a
/usr/lib/libunwind.a
/usr/lib/libunwind-ia64.a      /usr/lib/libunwind-setjmp.a
/usr/lib/libunwind.la
/usr/lib/libunwind-ia64.la     /usr/lib/libunwind-setjmp.la
/usr/lib/libunwind.so
/usr/lib/libunwind-ia64.so     /usr/lib/libunwind-setjmp.so
/usr/lib/libunwind.so.1
/usr/lib/libunwind-ia64.so.1   /usr/lib/libunwind-setjmp.so.0
/usr/lib/libunwind.so.1.2.0


Thanks and Regards
