- Subject: libgo patch committed: runtime.Caller should succeed without debug info
Further testing uncovered a small bug in the change to use the
libbacktrace library. The runtime.Caller function should succeed if we
get the PC, even if we don't have any debug info. Bootstrapped and ran
Go testsuite on x86_64-unknown-linux-gnu. Committed to mainline.
