Well, the unwind code is being pulled in for:
Unwind table index '.ARM.exidx' at offset 0xa3fb8 contains 1 entries:
0x9b300 <__divdi3>: 0x1 [cantunwind]
So back-tracking that may also help.

Yeah until you or someone can figure out how to get the .ARM.exidx
section from being placed in the .bss, a quick work-around would be to
provide an alternate code to clear the bss that does something like...
memset(bsp_section_bss_begin, 0, __exidx_start - bsp_section_bss_begin);
memset(__exidx_s
OK! So is there any immediate solution which can be tried?

I can see the following pertinent information:
[15] .bss NOBITS 001156e0 0a8fd8 00fab0 00 WA 0 0 32
The bss section starts at 0x1156e0, has size 0xfab0, and is writeable.
In the symbol table we can see:
7825: 001156e0 0 NOTYPE GLOBAL DEFAULT 15 bsp_section_bss_b
In arm/shared/startup/linkcmds.base these barriers are used to add
gaps in the memory layout at link-time to accommodate for the size
requirements of the MMU. xbarrier aligns the executable region,
robarrier aligns the read-only memory, and rwbarrier aligns the
read-write memory.

Hi,
I have attached the report containing outputs of arm-rtems4.11-size
and arm-rtems4.11-nm -S.
From arm-rtems4.11-nm -S I don't see how memset() is accessing .text
section. The start and end values for both are not overlapping.
Maybe this patch

Please avoid unnecessary white-space changes and white-space at the end
