My OS: Windows 7,32 Bit, Intel Centrino Core\*2 Duo, Toshiba A 205 Satellite,386 Pentium Laptop.  
My binUtils: GNU Assembler Version 2.9.4 using BFD version 2.9.4.

I am using NetBeans IDE 7.4 Version

The following error displays on the screen.

Program received signal sigsegv: segmentation fault-invalid memory reference.  
Backtrace for this error:  
#0 0x6f8aecb4  
#1 0x6f89d642  
#2 0x401138

waiting for your help to the above cited assembler troubles. I don’t know where is the fault lies in which routine.

Special request: If possible please refer me for fortran interface with assembler outsourcing works.All of us professionals and retired electrical,mechanical,chemical engineers with doctorates interested in fortran,assembler.Some professionals left/closed their fortran consultancies.Now we have only done fortran,assembler in  
Hyderabad,India from the last 30+ years.

This only request not a demand.

Waiting for your early response and also

expecting good news from your end.

Thanks
