GDB 5.0 segmentation faults on a DEC Alpha DS-10 running Digital Unix 5.0. I compiled gdb-5.0 with gcc 2.95.2 without errors. Starting gdb on the following one line program and running causes gdb to segmentation fault. Tom test.c: main() {} % gcc --version 2.95.2 % gcc -g -o test test.c % ./test % gdb ./test GNU gdb 5.0 Copyright 2000 Free Software Foundation, Inc.
