Hi Ramana,

I am working with Raghu and looking into the same crash issue.

Thanks for your suggestions till now. Due to some constraints , we cant move to
a new toolchain. We are looking forward to fix this issue in ARM9 toolchain
4.2.1.

Though we got a fix for this issue online, we need your expertise to port it to
our toolchain.

When we were searching for inputs, we came across following article.
https://sourceware.org/ml/libc-ports/2011-03/msg00045.html

In this article,  Ryosei Takagi was facing the same issue (at exact location)
and has provided a fix for it in __longjump.S.

This particular __longjump.S is not available in toolchain 4.2.1. I searched
for relevant code and couldnt find it. 

Since we are not much familiar with this toolchain code, its taking more time
than expected to understand and port the code. So, need your valuable advise to
find the relevant location to port this fix.

If you need additional information, please let me know. 

Thank you,
Murali
