[fpc-pascal] invalid floating point

[John Lee]

Running win32 fpc 2.7.1 10/01/2014

Compiling with no -v options.I get

An unhandled exception occurred at $0043C670:37
EInvalidOp: Invalid floating point operation
  $0043C670  REGRESS,  line 347 of c:/com/livel.pp

When I check what this line no is it is last line of a procedure regress
which does linear regression calcs.

I've normally got more line no info for fpu problems eg the line in regress
at which it went wrong, which would be helpful.

Have the defaults re line nos changed in latest 2.7.1s?. Do I have to
compile with -vl to get more info?

Any ideas on how to fix welcome.
John
