From 31013836a71e07751a6827f9d2ad41ef502ddaff Mon Sep 17 00:00:00 2001 From: Nicolas Boichat Date: Thu, 11 Jul 2019 20:52:27 -0700 Subject: [PATCH] scripts/decode_stacktrace: match basepath using shell prefix operator, not regex The basepath may contain special characters, which would confuse the regex matcher. ${var#prefix} does the right thing.
