I have the same problem for the gdb/g++. For a simple program it looks as
though you can ignore the error using the 'continue' command:
(gdb) run
Starting program: /home/e1/prog/plus
"/usr/lib/libcrypt.a": not in executable format: File format not recognized.
(gdb) step
Single stepping until exit from function __start,
which has no line number information.
main () at plus.cc:4
4 int i, sum=0;
(gdb) cont
Continuing.
sum of squares 1 to 10: 285
Program exited normally.
I would like to know what the consequences are for more complicated
programs. I cannot convert the file format. e.g. if I try ar -g libcrypt.a I
get an error message:
ar: 0707-130 The archive contains one or more 64-bit objects. It cannot be
converted to the small archive format.
If I extract all files and build a new library without the 64bit files the
libcrypt.a I can use the -g flag and the error has disappeared. (But I get
the same error for libc.a. I guess I have to rebuild all libraries for 32
bit.
Anyone tried this already?

Elizabeth-
Yes, I've seen similar problems on AIX 4.3.x. My guess is that gdb doesn't
understand "big format" libraries (run
file /usr/lib/libcrypt.a
to see what I mean), though that is just a guess. I've encountered other
difficulties with gdb on AIX in the past (even prior to versions with big
format libraries).
The gdb team would probably welcome patches contributed from an
AIX-knowledgeable person (any IBM engineers listening?!) that enhances
gdb's support for AIX. HP did it to improve gdb's support of HP-UX, so
maybe IBM will follow suit. I wouldn't hold my breath, though.
