Hello, FSF people.

I got a fatal error signal from gcc when compiling a short filter program.
I'm not sure it's a known bug or not, so I decided to report this anyway.
My system is hp9000 model 730 with HP-UX 8.07 running with 80MB of memory.
I'm using gcc-2.2.2, which was installed with "configure hp9k730", compiled
with debugging information generation enabled. (I'm not using this -g option
so far, as gdb seems not to support HP-UX PA-RISC)
I'm also using gas-1.36 ported to PA-RISC1.1 by the Utah-univ. group for gcc.
The version of my libg++ is 2.1.

Below is the code and the output from the compiler.
