I can confirm that this bug remains in both current head and 2011.08. I, too,
am building for a LEON3 SPARC v8 processor with a hardware FPU. uLibc fails in
just the same way for versions 0.9.31, 0.9.32, and today's daily snapshot.

uClibc master branch is still using HIDDEN_JUMPTARGET (like it should be).  the
proposed patch is wrong imo and really shouldn't be in buildroot, but i'll let
the BR guys worry about that.

why is your libc/misc/internals/__errno_location.c not being compiled with this
symbol ?  it should look like:
$ readelf -sW libc/misc/internals/__errno_location.os  | grep FUNC
     8: 0000000000000000     8 FUNC    WEAK   HIDDEN     1
__GI___errno_location
    11: 0000000000000000     8 FUNC    WEAK   DEFAULT    1 __errno_location

hidden weak handling is unfortunately pretty broken in recent gcc. Since (IIRC)
c++ and/or TLS handling elsewhere started to rely on this broken behaviour
chances are low that it will be fixed (as in behaviour of previous gcc
reinstated). An alternative was applied as
00f425b39b9258a78df47cebdd0d2c779753392f and the earlier
acfc107a50344b100b9ea492678928acc047c6ae

Hi,

tried with current master and the problem still exist.
Can you share your working environment data? (build system, gcc version,
binutils version)
Removing HIDDEN_JUMPTARGET still make it work.

best regards
 Waldemar
