Parsel import causes crash #294
Comments

Hey! This definitely looks like an issue with you lxml installation. |
|
lxml is not used directly in my project, but only as a dependency of parsel. |
parsel is a simple pure Python package; it imports lxml, like your code does. Maybe it imports some other lxml modules which cause issue, so 'import lxml' is not enough to reproduce it. Maybe the environment is different when you try 'import lxml' vs 'import parsel'. I'm not sure how to help with your case. It's very unlikely to be an issue with parsel itself. Clean install of the software could help, not sure. I'm closing this issue for now. If the issue is not resolved for you, you can try https://stackoverflow.com/ (using tag "scrapy" could help) |
An empty Python script with just the statement 'import parsel' causes a SIGILL. According to the backtrack it is caused by lxml, but 'import lxml' works fine. So I file a report here first. On another machine there is no crash, hardware infos are below the BT:
`Program received signal SIGILL, Illegal instruction.
