Configuration: config.gdb sun3os4
Machine: Sun-3's, SunOS 4.0.1
The makefile:
first try: CC = gcc CFLAGS = -I. -g -O TARGET_ARCH =
(TARGET_ARCH to null because of Sun's make. GCC is 1.35)
second try: same as first, but -traditional added to CFLAGS
third try: CC = cc CFLAGS = -I. -g -Bstatic
The results:
I thought the first try would work because I had run fixincludes after
building gcc and LIB was /appl/life1/gnu/lib/g++-include. I got a
warning about illegal pointer combination on line 204 of inflow.c.
Inflow.c was mentioned in the README regarding SunOS 4, so I checked
gcc-include/sys and none of those files were in the #includes for
inflow.c. I didn't check the includes of inflow. It core dumped
while/after reading the symbols of a programme (ie, before any prompt
appears).
So I decided to just flip on -traditional rather than worry about the
gcc-include headers. Same warning abut inflow.c and same core dump.
Maybe not identical, but from a visual observation in happened at the
same time.
So I went to the third try, not sure whether it was gcc or gdb which
was broken. cc made the same complaint about inflow.c. The gdb
binary also coredumped while/after reading the symbol table. dbx on
gdb (People under 17 not admitted) gives this:
================================================================

The same thing happens when I run it on emacs, gcc, personal
programmes, et al. Does anyone recognize this problem? Did I goof or
is it a gen-u-ine, home-grown bug?
