Segmentation fault error

[Jennifer Benner]

Hi all, I am currently running code that reads in multiple datasets, merging them into one dataset. I keep encountering a "segmentation fault" error. I've done some google searches and understand this relates to me accessing some form of memory I don't have access to.

Has anyone else seen this error before? What did you come up with for a solution? Is this simply a case of my data being too big too handle?

Note: I've previously run this code without error, so I don't believe it's a problem with syntax.

Jennifer,

you've done nothing wrong. If you are using Stata, Stata should not access the memory it hasn't got permissions for.
So it is either a Stata's developers error and you need to contact Stata's tech support, or you are using some Stata extensions (plugins) that may result in such a behavior, in which case you need to contact the plugin developer.

In principle, any case where Stata closes unexpectedly or "crashes" should be reported to the developers (StataCorp). They are usually very quick in fixing these kind of problems:

You may also want to update first and see whether the most up to date version of Stata still exhibits the same problem.

Best, Sergiy Radyakin

Hi Sergiy, thanks for your response. I am not using any plug-ins. I am however using a custom command. Would this also potentially invoke a segmentation fault error? If not, then I will reach out to Stata developers for a solution.

Thanks,
Jen

Hi,
This came up again for me while using reghdfe:
Segmentation fault: 11
Jennifer, was your problem due to the custom command? Wondering if it's a problem with the user written rehdfe.
Thanks,
Daniel
