yup... exactly what I meant... 
hmm, just a suspicion: maybe there is a bug in the libm ? I recently
compiled a program that makes heavy use of the FPU un some *very*
different platforms... NetBSD hp300, NetBSD SPARC, Solaris, IRIX and
Linux... on the 2 NetBSD systems it crashed but worked fine on everything
else... 
the program uses no hughlevel math, just addition, subtraction,
multiplication and sometimes division... it was definitely no division by
zero error...

never had this... but x11perf crashes and the last protocol entry was
something with stippeled rectangles ... hmm, the openwindows clock crashes
too, even when running on a different machine with display on the hp. the
hands are filled with a kind of stipple-pattern... but - the openwindows
cmdtool crashes. it's just a terminal emulator with nothing special, xterm
never crashes and textedit works... strange...

(grin) looks nice :-) 
a question: there seems to be a virtual memory hole somewhere... I suspect
I don't get all memory back when I compile something really big ( for
instance the X11R5 server... ) what do you think ? my fault ?
