920 |

|
# (one before the prologue and one after) with the same line number,
|
921 |

# but dwarf regards these as duplicates and discards one of them.

# Therefore the address after the prologue (where the breakpoint is)
|
923 |
|
|
# has no exactly matching line symbol, and GDB reports the breakpoint
|
924 |
|
|
# as if it were in the middle of a line rather than at the beginning.
