Bug report for gcc

Hardware:	Cubix QB3/386
OS:		System V Release 3.2
Versions:	gcc - 1.36
Configurations:	gcc - i386v
Problems:	Building gdb-3.[34] (i386-sysv3.2) with gcc causes gdb to
		memory fault and dump core when started up; while building gdb
		with the native C compiler does not.  (Also, gdb doesn't quite
		seem to have COFF down pat, yet.  Compare the output of gdb to
		the output of sdb below).
The gdb building process:
