Hi Guinevere, The failures seem to be due to "LWP" output (instead of "Thread") in test_gcore. I.e., test_corefile succeeds with === (gdb) PASS: gdb.threads/threadcrash.exp: test_corefile: loading_corefile info threads Id Target Id Frame * 1 Thread 0xf7dbe7e0 (LWP 476389) 0x00830cea in crash_function () at /home/tcwg-buildslave/workspace/tcwg_gnu_4/abe/snapshots/gdb.git~master/gdb/testsuite/gdb.threads/threadcrash.c:381 2 Thread 0xf7c6f3a0 (LWP 476390) do_spin_task (location=NORMAL) at /home/tcwg-buildslave/workspace/tcwg_gnu_4/abe/snapshots/gdb.git~master/gdb/testsuite/gdb.threads/threadcrash.c:139 3 Thread 0xf746e3a0 (LWP 476391) do_spin_task (location=SIGNAL_HANDLER) at /home/tcwg-buildslave/workspace/tcwg_gnu_4/abe/snapshots/gdb.git~master/gdb/testsuite/gdb.threads/threadcrash.c:139 4 Thread 0xf6c6d3a0 (LWP 476392) do_spin_task (location=SIGNAL_ALT_STACK) at /home/tcwg-buildslave/workspace/tcwg_gnu_4/abe/snapshots/gdb.git~master/gdb/testsuite/gdb.threads/threadcrash.c:139 5 Thread 0xf52fe3a0 (LWP 476395) __libc_do_syscall () at ../sysdeps/unix/sysv/linux/arm/libc-do-syscall.S:46 6 Thread 0xf646c3a0 (LWP 476393) __libc_do_syscall () at ../sysdeps/unix/sysv/linux/arm/libc-do-syscall.S:46 7 Thread 0xf5aff3a0 (LWP 476394) __libc_do_syscall () at ../sysdeps/unix/sysv/linux/arm/libc-do-syscall.S:46 (gdb) PASS: gdb.threads/threadcrash.exp: test_corefile: $thread_count == 7 === and then test_gcore fails with === (gdb) PASS: gdb.threads/threadcrash.exp: test_gcore: loading_corefile info threads Id Target Id Frame * 1 LWP 476440 0x00400cea in crash_function () at /home/tcwg-buildslave/workspace/tcwg_gnu_4/abe/snapshots/gdb.git~master/gdb/testsuite/gdb.threads/threadcrash.c:381 2 LWP 476442 do_spin_task (location=NORMAL) at /home/tcwg-buildslave/workspace/tcwg_gnu_4/abe/snapshots/gdb.git~master/gdb/testsuite/gdb.threads/threadcrash.c:139 3 LWP 476443 do_spin_task (location=SIGNAL_HANDLER) at /home/tcwg-buildslave/workspace/tcwg_gnu_4/abe/snapshots/gdb.git~master/gdb/testsuite/gdb.threads/threadcrash.c:139 4 LWP 476444 do_spin_task (location=SIGNAL_ALT_STACK) at /home/tcwg-buildslave/workspace/tcwg_gnu_4/abe/snapshots/gdb.git~master/gdb/testsuite/gdb.threads/threadcrash.c:139 5 LWP 476445 0xf7eadb04 in ??
