Exception occuring when calling cryptographic function

[SyedFahimuddinAlavi]

I am trying to execute the cryptographic algorithm on ibex. AES works fines but when adding bigger algorithm I am getting exception when calling cryptographic function. This algorithm requires memcpy etc. so I have removed --nostdlib flag. I am getting no clue of starting point of this problem because that code is running on other cores in simulation as well as on host.

Hello simple system
EXCEPTION!!!
============
MEPC:   0x0011683E
MCAUSE: 0x0000000B
MTVAL:  0x00000000

My embedded firmware memory requirements are as follows but I expect that is quite well under memory requirements

  riscv32-unknown-elf-size --format=berkeley examples/sw/simple_system/hello_test/hello_test.elf 
   text	   data	    bss	    dec	    hex	filename
  95220	   1712	   8644	 105576	  19c68	examples/sw/simple_system/hello_test/hello_test.elf

The execution fails as you can see below and it is due to above exception.

==================

Tracing can be toggled by sending SIGUSR1 to this process:
$ kill -USR1 1826827

Simulation running, end by pressing CTRL-c.

My Environment

Operating system:

Ubuntu Linux 22.xx
Version of the Ibex source code:

I am using IBEX head revision of last week.
