In PLy_output(), when the elog() call in the TRY branch throws an exception (this can happen when a statement timeout kicks in, for example), the PyErr_SetString() call in the CATCH branch can cause a segfault, because the Py_XDECREF(so) call before it releases memory that is still used by the sv variable that PyErr_SetString() uses as argument, because sv points into memory owned by so. Backpatched back to 8.0, where this code was introduced. I also threw in a couple of volatile declarations for variables that are used before and after the TRY. I don't think they caused the crash that I observed, but they could become issues. |
