This is a bug report made with RHIDE Version 1.4 (Sep 30 1997 23:06:59)
I am running MS-DOS 6.20 (Windows 3.11).
At the end of the message are some information collected by rhide - bug_report.
My problem is the following:
============================
Using gcc 2.8.1, I noticed some problems to debug some programs.
More precisely:
-In a program that contains #include "sub_prog.c", it is impossible
to follow the pointer while stepping with gdb (actually, I use rhide).
However, I have no problem if I include the sub-program directly into
the main file.
-With another subprogram, I get an error compliling the program with
"gcc -g -Wall -save-temps -c fit_gene.c"
>Compiling: fit_gene.c
>Assembler messages:
>fit_gene.s(4208) Error: Fatal error: C_EFCN symbol out of scope
>There were some errors
This occurs only with the "-g" option, and does not depend on the
other options. It does the same if I include the subprogram
directly into the main file.
Looking at fit_gene.s: "C_EFCN" does not show in this file, and
the line 4208 is the last line of the file.
If I compile without the "-g" option, everything is OK (except for
debugging)
