There's something odd going on with mips-elf gdb.base/interrupt.exp. It seems to be failing at random---this is the third time it's mysteriously appeared. The symptoms have been that the .log file contains: (gdb) PASS: gdb.base/interrupt.exp: call function a second time continue Continuing. PASS: gdb.base/interrupt.exp: continue data data FAIL: gdb.base/interrupt.exp: echo data (timeout) end of file The gdb testsuite is looking for the 'data' output, which as you can see is there, and so the testcase should pass. The problem seems to happen only when the machine is under other load---specifically, when the machine is trying to update its binutils & gdb. I suspect that dejagnu is not properly matching the regexp because the extra activity on the machine is causing it to be given the output in two or more pieces. The kernel and dejagnu versions on the two machines (mips-elf is on anubis with a 2.4 kernel, native & powerpc are on maat with 2.2) are different; hopefully, soon the dejagnu versions will be synchronized, which should help to narrow down the problem. If anyone's seen this before (especially if you fixed it!), I'd be interested to hear about it. -- - Geoffrey Keating
