--- Comment #2 from ian at gcc dot gnu.org <ian at gcc dot gnu.org> --- Author: ian Date: Mon Aug 3 17:54:50 2015 New Revision: 226525 URL: https://gcc.gnu.org/viewcvs?rev=226525&root=gcc&view=rev Log: PR go/67101 runtime: Remove call to __builtin_frame_address. __builtin_frame_address was only supposed to use nonzero arguments for debugging purposes. Calling it with nonzero arguments can have unpredictable results and uses are now marked unsafe when -Wframe-address is enabled.
