+* Date: Fri, 17 Apr 1998 14:12:51 +0200
+* From: Jean-Paul Jeannot <jeannot@gx-tech.fr>
+* Organization: GX Technology France
+* To: egcs-bugs@cygnus.com
+* Subject: identified bug in g77 on Alpha
+* 
+* Dear Sir,
+* 
+* You will find below the assembly code of a simple Fortran routine which
+* crashes with segmentation fault when storing the first element 
+*       in( jT_f-hd_T     ) = Xsp
+* whereas everything is fine when commenting this line.
+* 
+* The assembly code (generated with 
+* -ffast-math -fexpensive-optimizations -fomit-frame-pointer -fno-inline
+* or with -O5)
+* uses a zapnot instruction to copy an address.
+* BUT the zapnot parameter is 15 (copuing 4 bytes) instead of 255 (to copy
+* 8 bytes). 
+* 
+* I guess this is typically a 64 bit issue. As, from my understanding,
+* zapnots are used a lot to copy registers, this may create problems
+* elsewhere.
+* 
+* Thanks for your help
+* 
+* Jean-Paul Jeannot
