Description Tom de Vries 2022-04-13 05:50:44 UTC

On openSUSE Tumbleweed, there's a cluster of FAILs related to pipe system call in this test-case:
...
FAIL: gdb.base/catch-syscall.exp: without arguments: syscall pipe has returned
FAIL: gdb.base/catch-syscall.exp: with many arguments: program has called pipe
FAIL: gdb.base/catch-syscall.exp: with many arguments: syscall pipe has returned
FAIL: gdb.base/catch-syscall.exp: with many arguments: program has called write
FAIL: gdb.base/catch-syscall.exp: with many arguments: syscall write has returned
FAIL: gdb.base/catch-syscall.exp: with many arguments: program has called read (the program exited)
FAIL: gdb.base/catch-syscall.exp: with many arguments: syscall read has returned (the program is no longer running)
FAIL: gdb.base/catch-syscall.exp: with many arguments: continue until exit (the program is no longer running)
FAIL: gdb.base/catch-syscall.exp: without args noxml: pipe: program has called 22
FAIL: gdb.base/catch-syscall.exp: without args noxml: pipe: syscall 22 has returned
FAIL: gdb.base/catch-syscall.exp: with args noxml: program has called 22
FAIL: gdb.base/catch-syscall.exp: with args noxml: syscall 22 has returned
FAIL: gdb.base/catch-syscall.exp: with args noxml: program has called 1
FAIL: gdb.base/catch-syscall.exp: with args noxml: syscall 1 has returned
FAIL: gdb.base/catch-syscall.exp: with args noxml: program has called 0 (the program exited)
FAIL: gdb.base/catch-syscall.exp: with args noxml: syscall 0 has returned (the program is no longer running)
...

And these look related:
...
FAIL: gdb.reverse/pipe-reverse.exp: continue to breakpoint: marker2
FAIL: gdb.reverse/readv-reverse.exp: continue to breakpoint: marker2
...

First in more detail:
...
(gdb) PASS: gdb.base/catch-syscall.exp: without arguments: program has called pipe
continue^M
Continuing.^M
^M
Catchpoint 2 (returned from syscall pipe2), 0x00007ffff7daabdd in pipe () from /lib64/libc.so.6^M
(gdb) FAIL: gdb.base/catch-syscall.exp: without arguments: syscall pipe has returned
...
