absolute relocation in TextSegment failed when loading a shared lib on arm7


Hi,

I think there is a problem with the handling of absolute relocations in
text segment of shared libraries in glibc when using arm7 controller.

In our example there should be an absolute relocation on label "rel".
The relocation table for the library seems to be ok:

RELOCATION RECORDS FOR [.text]:
OFFSET   TYPE              VALUE
00000008 R_ARM_PC24        .text
00000010 R_ARM_ABS32       a_function

But when loading libtest.so with the programm test on arm720t boards, we
got a segfault in the relocation code. I can't be more specific cause I
am not able to symbolic debug in the reloc function.
It seems that a relocation of type R_ARM_ABS32 in the .text segment
doesn't work. An absolut relocation in the .data segment works fine.
when linking statically everything works fine too.

We used a toolchain with gcc-3.4.4 and glibc-2.3.5 which was build with
crosstool-0.38 without any changes.
The code runs fine on i386 and on another arm9 machine. we have heard
that it also runs fine on other arm7 boards, build with a different
toolchain. we also tried other versions with gcc-3.3.4 and glibc 2.3.2
and even in the newest glibc 2.3.6 we got the segfault (all build with
crosstool).

As far as I can see the format of the shared library is ok (see below
for more info). thats why i think this is a glibc problem.

Thanks!
Christian
