Hi,

PR 544 des gdb.cp/annota2.exp and gdb.cp/annota3.exp sometimes FAIL with:
	FAIL: gdb.cp/annota3.exp: annotate-quit (pattern 1)

It gets reliably reproducible for me (Fedora 8 x86_64) if GDB gets straced:
	mv gdb gdb-orig
	wget -O gdb http://cvs.jankratochvil.net/viewcvs/nethome/src/gdb-wrap?rev=HEAD

The problem is that if usually CTRL-C is hit during poll(2) and everything is
fine.  But if CTRL-C is hit inside readline processing its RL_SIGNAL_HANDLER
gets called which calls RL_FREE_LINE_STATE and $gdb_prompt gets displayed twice
and GDB_EXPECT or GDB_EXPECT_LIST are not patient enough to see later
^Z^Zerror-begin+Quit+^Z^Zquit.

Unaware how to easily detect a failure without timing out.


Regards,
Jan
