platform: Linux x86_64 (CentOS) kernel: 2.6.18-128.1.10.el5.centos.plus python version: 2.4.3 PyQt versin: 4.7.3 subprocess is generating a segmentation fault. I am running a proprietary quicktime generating script inside my own (Qt) script using the subprocess module. I am piping both stdout and stderr into my script. I have tried reading these two with .communicate() and with the <Popen>.stdout / <Popen>.stderr properties. Both end up generating the following error: *** glibc detected *** /usr/bin/python: corrupted double-linked list: 0x00000000161c5c50 *** Segmentation fault running my script, and using os.system() to run the proprietary script works just fine The (C++ compiled) proprietary script does not appear to have any problems crashing under normal circumstances, and I am assuming if there was a problem with the proprietary script, it wouldn't cascade to crashing my own script |

Well, without a non-proprietary way to reproduce the failure it is going to be a little hard to debug. You could try debugging it with gdb. |

> python version: 2.4.3 I'd suggest to try this with Python 2.6 or later. 2.4 and 2.5 are in security-fix only mode. |

Without more information and a way of reproducing on a recent version of Python, this can't progress. Closing as "works for me". |
