[PATCH] Fix config_file file leak.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

We are using Sentry (a C/C++ static analysis tool) to analyze
git on a nightly basis. Sentry found that a file leak
was recently introduced in the commit 924aaf3.

I'm hoping the attached patch correctly fixes up this leak.

Thanks,
Chris
