https://bugzilla.suse.com/show_bug.cgi?id=1195689 Bug ID: 1195689 Summary: libsolv segfault when using python API Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.2 Hardware: x86-64 OS: openSUSE Leap 15.3 Status: NEW Severity: Normal Priority: P5 - None Component: libzypp Assignee: zypp-maintainers@suse.de Reporter: mathias.reitinger@loop0.org QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I'm using libsolv via the python bindings and am hitting a segfault when performing problem resolution. This is using a custom build of rpm (4.17.0) and libsolv (0.7.20) to verify the issue persists with the latest version but I can reproduce this with rpm/libsolv as shipped by Leap 15.2 as well. This happens when calling element.Job() on the list of solution elements. relevant pysolv part: https://github.com/openSUSE/libsolv/blob/master/examples/pysolv#L796 Backtrace from gdb: (gdb) t a a bt full Thread 1 (Thread 0x7ffff7fd7540 (LWP 25152) "python3"): #0 0x00007ffff2c1e69a in solver_solutionelement_extrajobflags (solv=0x55555589f880, problem=<optimized out>, solution=<optimized out>) at /usr/src/debug/atikon-bb-libsolv-0.7.20-lp152.35.1.x86_64/src/problems.c:974 solidx = <optimized out> #1 0x00007ffff235e9c5 in Solutionelement_Job (self=0x555555ac88c0) at /usr/src/debug/atikon-bb-libsolv-0.7.20-lp152.35.1.x86_64/bindings/python3/solv_python.c:5673 extraflags = <optimized out> extraflags = <optimized out> #2 _wrap_Solutionelement_Job (self=<optimized out>, args=<optimized out>) at /usr/src/debug/atikon-bb-libsolv-0.7.20-lp152.35.1.x86_64/bindings/python3/solv_python.c:18344 resultobj = 0x0 arg1 = 0x555555ac88c0 argp1 = 0x555555ac88c0 res1 = <optimized out> obj0 = <Solutionelement(this=<SwigPyObject at remote 0x7ffff231f330>) at remote 0x7ffff2334828> result = 0x0 fail = <optimized out> #3 0x00007ffff79b0bfd in _PyCFunction_FastCallDict (func_obj=<built-in method Solutionelement_Job of module object at remote 0x7ffff260ddb8>, args=0x7ffff22d26e0, nargs=<optimized out>, kwargs=<optimized out>) at Objects/methodobject.c:234 tuple = (<Solutionelement(this=<SwigPyObject at remote 0x7ffff231f330>) at remote 0x7ffff2334828>,) func = 0x7ffff25d8360 meth = 0x7ffff235e960 <_wrap_Solutionelement_Job> self = <module at remote 0x7ffff260ddb8> result = <optimized out> flags = <optimized out> #4 0x00007ffff7a22582 in call_function (pp_stack=pp_stack@entry=0x7fffffffd778, oparg=<optimized out>, kwnames=kwnames@entry=0x0) at Python/ceval.c:4851 tstate = 0x555555609450 pfunc = 0x7ffff22d26d8 func = <built-in method Solutionelement_Job of module object at remote 0x7ffff260ddb8> x = <optimized out> w = <optimized out> nkwargs = <optimized out> nargs = <optimized out> stack = <optimized out> -- You are receiving this mail because: You are on the CC list for the bug.
