Bug in gcc CVS HEAD from a few days ago with alloca and stack alignment

Sat Feb 10 19:49:00 GMT 2001

Hi David,
Thanks! 
I changed STACK_BOUNDARY to 128 and rebuilt the entire gcc and now everything 
has started working including the gcj closure code and the gij interpreter.
Will you please commit a proper fix? Franz's mail machine bounced my last 
mail so I don't think he knows about this problem.
Take care,
Kevin
