* | Fix two instances of integer-assignment to string.Henner Zeller2019-05-142-2/+3
| | | | | | | | | | | | | | | | | | o In cover.cc, the int-result of mkstemps() was assigned to a string and silently interpreted as a single-character filename with a funny value. Fix with the intent: assign the filename. o in libparse.cc, an int was assigned to a string, but depending on visible constructors, this is ambiguous. Explicitly cast this to a char.
