When running the one liner perl calculator described in
this group, I sometimes get a weird "bad free()" error:

% perl -pe 's/^.*$/(eval $&).$@/e;'
sin(2)
0.90929742682568170942
sin(3.14159)
Bad free() ignored, <> line 2.

The system is a Sun Sparcstation-1 (4/60) running release 4.1
of Sun OS.  The Perl was release 3.0, patchlevel 18, compiled
with the standard Sun C compiler.  I can replicate the problem
on other Sun SPARC systems running 4.0.3 and 4.1 Sun OS,
but it does not occur on Sun-3 (68020 CPU) or VAX systems.

I suspect a bug in Sun OS or perl, but
I'm not sure where to look at this point.
