gcc 2.9.5 bug -- mvp-0-2

[Allan Frankel <allan at mvp-fw dot visionpro dot com>]

This file leaks memory badly if compiled -O2 but not with -O0.  The problem also
goes away if the string class stuff is recoded with sprintf.  The command line
and compiler log messages from the --save-temps run are appended below.  The
resulting algoinit.ii preprocessed source was gzip'd, uuencode'd, and split into
two pieces which follow in separate mesages with subjects of mvp-1-2 and mvp-2-2.

I am happy to help further if needed, but since we do have a workaround, I do
not plan on investigating further unless requested.

Thanks,
	Allan Frankel, allan@visionpro.com
