From b1b53fb3ef077bf4412da53f0057b9c0e9ed4f3e Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Thu, 21 Jul 2016 09:15:21 +0100 Subject: [PATCH] Fix fail in gdb.server/solib-list.exp If I run single test solib-list.exp, it is OK. If I run two, as below, there are fails, $ make check RUNTESTFLAGS="server-run.exp solib-list.exp" FAIL: gdb.server/solib-list.exp: non-stop 0: continue (the program exited) FAIL: gdb.server/solib-list.exp: non-stop 0: p libvar FAIL: gdb.server/solib-list.exp: non-stop 1: continue (the program exited) FAIL: gdb.server/solib-list.exp: non-stop 1: p libvar in gdb.log, /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/../../gdb/gdbserver/gdbserver --once :2347 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.server/server-run/server-run /lib64/ld-linux-x86-64.so.2 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.server/solib-list/solib-list server-run is spawned, which is wrong.
