We use a call to strncpy to work around a TSAN bug (wherein TSAN only delivers asynchronous signals when the thread receiving the signal calls a libc function). Unfortunately, GCC 7 inlines the call, avoiding the TSAN libc trap entirely. Per Ian's suggestion, use global variables as strncpy arguments: that way, the compiler can't make any assumptions about the concrete values and can't inline the call away. fixes #21196 Change-Id: Ie95f1feaf9af1a8056f924f49c29cfc8515385d7 Reviewed-on: https://go-review.googlesource.com/55872 Reviewed-by: Ian Lance Taylor <iant@golang.org> |
