Bug report for gdb-3.3
Hardware: Cubix QB3/386
OS: System V Release 3.2
Versions: gdb - 3.3
gcc - 1.36
Configurations: gdb - i386-sysv3.2
gcc - i386v
Problems: Building gdb with gcc causes gdb to memory fault and dump
core; while building gdb with the native 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 building process:
