Bug Report for GCC:
-------------------
Problem :  gcc 1.28 gets a fatal signal for the following program, taken
           from the gdb+ distribution (inflow.c).  I would have included
           the gdb+ output and stack trace, but I stripped the 1.28 compiler
           of its symbols, and am unable to recompile it due to the
           mysterious ``bit-rot bug'' with sparc (sorry John ;-)).

1.) Version : gcc 1.28
