I am not counting  on line numbers.  The debugged program exited only after 
evaluating the second line.
I also verified it by adding a "die" line between the lines – and then the 
script dies without the error.

Don't count on the exact line numbers. They can seem a bit off. There are 
various reasons for this and they all make sense once you read up on them. 
Short answer though: don't think of the line numbers as exact.

Your problem is clearly the input, as we've all said. :)

Now the question is, how did you reach such input?
(it does help though that the error message contains the line number in the 
faulty input handle)

Gabor,
Yes, I did try it with perl debugger  (line numbers changed from first mail):
 
  DB<2> n
main::funcMap(./cpp2idl.pl:707):                    my 
$retValType=$retVal->{'type'};
                                                                                                                   
 DB<2> n
main::funcMap(./cpp2idl.pl:708):                    if ($retValType =~ 
m/^struct/)
main::funcMap(./cpp2idl.pl:709):                      {
                                                                                                                   
 DB<2> print $retValType
enum eAsonTrailRate
                                                                                                                   
 DB<3> s
Can't use string ("enum eAsonTrailRate") as a HASH ref while "strict refs" in 
use at ./cpp2idl.pl line 708, <$fh> line 163.
at ./cpp2idl.pl line 708
        main::funcMap('eAsonTrailRate') called at ./cpp2idl.pl line 416
        main::processNewStruct('eAsonTrailRate', 0) called at ./cpp2idl.pl line 
366
        
main::processFile('/auto/enm_proj/XDM_phase_VIII/EMS8.2R3NG/inc/imnmstrailinfo.h')
 called at ./cpp2idl.pl line 59
IO::Handle::DESTROY(/auto/enm_soft/i86pc/perl/lib/5.8.8/i86pc-solaris/IO/Handle.pm:333):
333:    sub DESTROY {}
 
As you can see, the debugger sees $retValType as a simple string, that was set 
in line 707, but the program exit with error.
The strangest thing here, is that line 708 has no de-refencing at all, it is in 
the previous line that it happened.
