[Bug gdb/18436] Can't print dynamically allocated global array

--- Comment #9 from stanton at haas dot berkeley.edu ---
I just noticed something odd. Using gcc 5.1 and gdb 7.7.1 (both MacPorts), I
can inspect v[0] fine if I compile like this:

gcc -g main.c -o main

It fails if I compile the same program (same gcc, some gdb) like this:

gcc -g -c -o main.o main.c
gcc -o main main.o 

Any idea why this should be different?
