From c316c0b29d9991a231bdcbab0fcdc51114cddd13 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Tue, 17 Aug 2021 15:23:41 -0400 Subject: gdb: fix thread_step_over_chain_length If I debug a single-thread program and look at the infrun debug logs, I see: [infrun] start_step_over: stealing global queue of threads to step, length = 2 That makes no sense... turns out there's a buglet in thread_step_over_chain_length, "num" should be initialized to 0. I think this bug is a leftover from an earlier version of the code (not merged upstream) that manually walked the list, where the first item was implicitly counted (hence the 1).
