>Description:
The testfile xxx.c causes various ICEs.  It was derived from compile/20010605-1.c.  Currently, compile/20010605-1.c fails on the PA.  Since there is a problem with the return of a variable sized type in a nested function, I wondered if there would also be with a variable sized parameter in a nested function.

With gcc-3.0.1 on the PA:

266 (hiauly1)dave> gcc -o xxx xxx.c
xxx.c: In function `block_parm':
xxx.c:13: Internal compiler error in size_binop, at fold-const.c:1914

On the PA, there is a problem with pa.h not doing appropriate checks after calling int_size_in_bytes for a return of -1.
However, even with this fixed, the test code still causes an ICE.  Part of the problem is assign_parms is called before the static chain list is built.
