Remote debugging on ARM and shared libraries

Hello,

I am trying to debug a program remotely on an ARM target
with
gdbserver and I get a GDB segmentation fault when I try to
step on a
symbol in a shared library (printf for example). This is the
exact
same problem as here (bug in get_frame_pc):
http://sources.
redhat.com/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&da
tabase=gdb&pr=1992
It works with my native debugger so maybe I am doing
something wrong,
I tried to play with solib-search-path and
solib-absolute-prefix with
no results on my host. Would you have any idea?

My GDB version:
$ arm-linux-gdb.exe -v
GNU gdb 6.4

This GDB was configured as "--host=i386-pc-cygwin
--target=arm-linux-uclibc".

Thanks in advance,

This has been just about the most frequently reported bug
lately.  One
potential patch was here:
  http://sourceware.org/ml/gdb-patches/2006-02/msg00387.
html

But I need to try a different approach after talking to Mark
about it.

Joel, I think we need to fix this one before the release of
gdb 6.5
(though certainly it doesn't need to hold up the branch).
