The logical breakpoints map was created as a side effect of createUnrecoveredPanicBreakpoint or createFatalThrowBreakpoint, however with an executable with incomplete debug info (that must be incomplete in just the right way) both will fail and the logical breakpoint map will never be created. It's unknown how such an executable could be created, one easy way is to debug a non-go executable. Fixes go-delve#3114
