Summary Reproducible: Always
Please provide the output of "emerge --info" as you were asked when filing the bug report. It provides us valuable information about your system and how the packages were built. Also, please provide the console output when libpcre segfaults as it might provide some further insight as to the problem. Finally please describe the problem with a few more words than simply "segfault at runtime". Does this happen every time? Does it happen immediately? Is there any information in the output from dmesg, in the syslogs, or on the console that might be pertinent? In general, the more information you can provide us with, the more likely we are to be able to help and that more likely that your bug will eventually get solved.
