This mailing list has very little activity.  I don't know and would
normally comment but I hate to see people post questions and then not
get any response at all.  Therefore I will comment here in the hope
that I might be able to get you to a better place to ask your question.

Upgrading what from version 7 to what version 9?  What is being
upgraded?

The BSS section is normally used to store static data.  In a C program
if one is defining a variable with initialized data then this will go
into the BSS section.

  int iii = 42;

It makes no sense if the BSS segment is larger than the file size.  It
makes me thing there is a data corruption problem.  Or perhaps the
file system is full and part of the file could not be written.  Or
potentially other problem of which this is only a down stream cascade
failure with a different root cause.

Memory exhausted indicates that the program tried to allocate memory
or tried to fork and whichever action it was failed due to being out
of virtual memory.

I would look to see if the storage filled up.  I would look to see if
whatever you are doing ran out of memory.

Since this is ARM I assume some type of NAND flash file system.  In
which case I would look for a failure of the storage such as due to
worn out storage cells.  If it is an SD card I would try reading from
every byte and verifying that the storage device is working okay.  I
have had SD cards using NAND storage and other similar devices fail
creating file corruption.
