> Project: Traffic Server
> Issue Type: Bug
> Components: HTTP
> Reporter: Mark Moseley
>
> ATS 4.1.1, Ubuntu Precise 64-bit, Intel
> With proxy.config.remap.num_remap_threads set 8, using a url_regex in cache.config yields a segfault with the below stacktrace.
> I don't get a segfault with proxy.config.remap.num_remap_threads=0 nor proxy.config.remap.num_remap_threads=1, using url_regex in cache.config.
> I also have no issues with proxy.config.remap.num_remap_threads=8 but using dest_domain instead of url_regex.
> The url_regexes I tried:
> url_regex=/
> url_regex=.
