- Subject: [obv] entry-values debug: Fix PC 0x0 output
Hi,
with "set debug entry-values 1" GDB could sometimes print
Unable to find function for PC 0x0
instead of the valid PC it could not resolve.
Normally such error also should not happen; but that will be a different
patch.
Checked in as obvious.
Jan
