Debugging information/libc.so.4

[Marcelo Magallon <mmagallo@efis.ucr.ac.cr>]

Hi, I'm having a little trouble with a program I'm working on, and I'd 
like to use gdb to see what's going on, but when I try to include debug 
information at compilation time I get:

$ gcc -o lentes -g Lentes.c graphics.c -lm

ld: Output file requires shared library `libc.so.4'
gcc: Internal compiler error: program ld got fatal signal 6

The compilation goes ok when I don't use the -g switch...

when I do ldconfig -v to see if libc.so.4 in on ld's "path", I get (sorry 
to include all the output, but I think it may helpful)

$ /sbin/ldconfig -v

Just for the record... do you see any problem in the following snip of
code? Am I so tired I can see the obvious? I have successfully ran the
program when compiled on a i486/Turbo C/MSDOS, i486/djgppv1(GCC)/MSDOS,
Alpha/Digital CC/OSF, Alpha/GCC/OSF, but I *need* it on a
i486/GCC/Debian Linux

void DumpScreen(tScreen * screen, const char *basename, char format,
  char verbose)
{
/*stuff deleted*/
   char *workfile="00000000.000";
/*stuff deleted*/
   strncpy(workfile,basename,4); /* the program core dumps here */
/*stuff deleted*/
}

Thanks for any help...
