Floating Point exception when compiling frmcmp.sh .

I am trying to compile a form on a 10.1.0 Forms instance. 

I have compiled many times on this server with no problems.

Now when I try to compile I get

/u01/oracle/product/10.1.0/mt/bin/frmcmp.sh: line 63: 28748 Floating point exce*

The complaining line is the last line.

$ORACLE_HOME/bin/frmcmp $*

Any ideas?

Uploaded in binary and checked the file sizes.  All that seems fine.

Scratching my head....

Thanks
