I believe I have discovered a bug in gcc for the sparc (sun4) machines.
This bug was also reported to comp.windows.x by William J. Ray on 22 Dec
1988.

The bug was discovered independently by Mr. Ray and myself while
attempting to use gcc to compile the X11R3 sample server program.  While
attempting to compile the file "sunInit.c" in server/ddx/sun, the compiler
aborts with the message:

gcc: Program cc1 got fatal signal 6.

I have walked through the code in sunInit.c in an attempt to narrow down
the problem and can reproduce the bug with a 20 line program.  I have
included the program with this report.


VITAL STATISTICS:
Machine: Sun 4/110 with Sun OS 4.0
GCC Version: 1.31
tm file: tm-sparc.h
.md file: sparc.md

============================== C SOURCE FILE ==============================
typedef struct {
	int a;
	int b;
	int c;
} Something;

Something those_things[2];

typedef struct {
	Something things[10];
} Big_thing;

main()
{
	Big_thing *big_thing_p;
	int i;

	for (i = 0; i < 2; i++)
		big_thing_p->things[i] = those_things[i];
}
===========================================================================

compile the above with

$ gcc prog.c

(no special arguments)


If I can be of further help in repairing this bug, please let me know
