Hi Sergio,
Yes, that is one issue I've seen before on Ubuntu.  I switched to
gcc trunk, then I can run gdb.compile/*.exp tests on Ubuntu.
Thanks!

There is only one fail,

bt^M
#0  _gdb_expr (__regs=0x7ffff7ff3000) at gdb command line:1^M
#1  <function called from gdb>^M
#2  main () at /home/yao.qi/SourceCode/gnu/build/gdb/testsuite/../../../binutils-gdb/gdb/testsuite/gdb.compile/compile.c:106^M
(gdb) FAIL: gdb.compile/compile.exp: bt

On fedora builder, the test passes,
bt^M
#0  0x00007ffff7ff43f6 in _gdb_expr (__regs=0x7ffff7ff2000) at gdb
command line:1^M
#1  <function called from gdb>^M
#2  main () at /home/gdb-buildbot/fedora-x86-64-1/fedora-x86-64/build/gdb/testsuite/../../../binutils-gdb/gdb/testsuite/gdb.compile/compile.c:106^M
(gdb) PASS: gdb.compile/compile.exp: bt

I'll fix it in test case.
