C program compiles, but debugger isn't happy. These red warning lines appear:

GNU gdb (Ubuntu 7.7.1-0ubuntu5~14.04.2) 7.7.1
. . .
Type "apropos word" to search for commands related to "word".
No line 382 in file "/home/bogwan/Computer/eclipse/dedup/dedup.c".
No line 383 in file "/home/bogwan/Computer/eclipse/dedup/dedup.c".
No line 385 in file "/home/bogwan/Computer/eclipse/dedup/dedup.c".

There are 393 lines in the file. I wonder if this might be related to the scroll problem I over-reported.

A debug-compiled program file contains line-number records. It seems that GDB is not finding them in your executable file. To be debuggable, a program must be both compiled and linked with debugger flags. Also, to avoid weird line number associations with the actual code, it is advisable to compile without optimization. The debugger cannot always follow the transformations optimization does.
