Subject: Illegal Instruction on ia64

Hi,
    We are compiling an Fortran application on ia64 running Linux. The following 
compiler is used for the purpose.

Intel(R) Fortran Itanium(TM) Compiler for Itanium(TM)-based applications
Version 6.0 

The execution of it results in an "Illegal instruction". This happens at a point when 
we are trying to 'deallocate' large chunk of memory.

Using gdb we got the following:

Program received signal SIGILL, Illegal instruction.
0x200000000029fe70 in chunk_free (ar_ptr=0x20000000003f39b0, p=0x6000000000b6a1b0)

Can you please let me know whether this is an OS  related issue.
