Huh.  So it called exit(1) somewhere, without generating any error
message first.  That's pretty unfriendly.  Try setting a breakpoint
at exit(), and if you can get it to stop there, get a stack trace
from that point.

Dunno if you're familiar with gdb, but the quick way to do this is
to say
    b exit
and then the "run" command.  It's possible that the attempt to set
the breakpoint will fail because libc.so isn't loaded yet, in
which case you need two steps:
    b main
    run ...
    when control stops at main:
    b exit
    continue
