New submission from Claudiu.Popa: Given the following code, tracemalloc crashes with: "Floating point exception: 8 (core dumped)"
import tracemalloc tracemalloc.start(10) import io io.StringIO() The culprit is this line "assert(nelem <= PY_SIZE_MAX / elsize);" from tracemalloc_alloc. elsize is 0 from stringio.c, "self->buf = (Py_UCS4 *)PyMem_Malloc(0);". The attached patch skips the assert if elsize is 0, but I don't know if this is the right approach. Thanks! ---------- components: Library (Lib) files: tracemalloc.patch keywords: patch messages: 219587 nosy: Claudiu.Popa, haypo priority: normal severity: normal status: open title: tracemalloc crashes with floating point exception when using StringIO type: crash versions: Python 3.5 Added file: http://bugs.python.org/file35450/tracemalloc.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21639> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
