I think I understand what is happening. The SLES buildbots do not have debugging symbols for glibc: (gdb) set verbose on (gdb) break builtin_id Reading in symbols for Python/bltinmodule.c...done. Breakpoint 1 at 0x139403c: file Python/bltinmodule.c, line 1182. (gdb) r Starting program: /home/linux1/cpython/python tester.py Reading symbols from /lib/ld64.so.1...(no debugging symbols found)...done. Reading symbols from system-supplied DSO at 0x3fffdffe000...(no debugging symbols found)...done. Missing separate debuginfos, use: zypper install glibc-debuginfo-2.22-62.13.2.s390x Reading symbols from /lib64/libpthread.so.0...(no debugging symbols found)...done. [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1". Reading symbols from /lib64/libdl.so.2...(no debugging symbols found)...done.

Reading symbols from /lib64/libc.so.6...(no debugging symbols found)...done. And when requesting the stacktrace of a thread it cannot go into libc because the program counter is not available: (gdb) thread apply 2 where #19 0x0000000001324f02 in method_call (method=<method at remote 0x3fffdeee258>, args=(), kwargs=0x0) at Objects/classobject.c:306 #20 0x0000000001047396 in PyObject_Call (callable=<method at remote 0x3fffdeee258>, args=(), kwargs=0x0) at Objects/call.c:245 #21 0x00000000012b91be in t_bootstrap (boot_raw=0x3fffd9fb118) at ./Modules/_threadmodule.c:992 #22 0x000003fffde88b22 in start_thread () from /lib64/libpthread.so.0 #23 0x000003fffdb7164a in thread_start () from /lib64/libc.so.6 PC not saved This get triggered when printing the python stack trace with py-bt and the exception is getting printed on stderr and this fails the test. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34007> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
