--- Comment #1 from ian at gcc dot gnu.org <ian at gcc dot gnu.org> --- Author: ian Date: Mon Mar 9 23:40:58 2015 New Revision: 221291 URL: https://gcc.gnu.org/viewcvs?rev=221291&root=gcc&view=rev Log: PR go/65349 runtime: Don't call malloc from __go_file_line callback. When crashing, we call runtime_printcreatedby which calls __go_file_line which used to call the Go malloc. If we are crashing due to a signal due to heap corruption of some sort, the GO malloc lock might already be held, leading to a crash within a crash. Avoid that by assuming that the libbacktrace strings will stick around, as we already do in go-callers.c. Modified: trunk/libgo/runtime/go-caller.c
