I'm getting testsuite failures from gdb.base/pending.exp.  This is
i686-pc-linux-gnu (Red Hat 8.0, if that matters), lots of different
GCC's.

Usually, I get this:

FAIL: gdb.base/pending.exp: set pending breakpoint
FAIL: gdb.base/pending.exp: single pending breakpoint info
FAIL: gdb.base/pending.exp: pending plus real breakpoint info
FAIL: gdb.base/pending.exp: pending plus condition
FAIL: gdb.base/pending.exp: pending disabled
FAIL: gdb.base/pending.exp: pending disabled plus commands
FAIL: gdb.base/pending.exp: multiple pending breakpoints
FAIL: gdb.base/pending.exp: re-enabling pending breakpoint that can resolve instantly

but sometimes I get this:

FAIL: gdb.base/pending.exp: set pending breakpoint
FAIL: gdb.base/pending.exp: single pending breakpoint info
FAIL: gdb.base/pending.exp: pending plus real breakpoint info
FAIL: gdb.base/pending.exp: pending plus condition
FAIL: gdb.base/pending.exp: pending disabled
FAIL: gdb.base/pending.exp: pending disabled plus commands
FAIL: gdb.base/pending.exp: Set pending breakpoint 2
ERROR: Got interactive prompt.
ERROR: Got interactive prompt.
FAIL: gdb.base/pending.exp: re-enabling pending breakpoint that can resolve instantly
FAIL: gdb.base/pending.exp: continue to resolved breakpoint 2
FAIL: gdb.base/pending.exp: continue to resolved breakpoint 1

Log attached.
