objdump assertion failure

[Sami Kantoluoto]

Hi,

I'm getting following message when using "mcore-elf-objdump -g <obj>" on
some object files:

assertion "info->stack->visibility != DEBUG_VISIBILITY_IGNORE" failed: file
"/pub/devel/gnu/binutils-2.11.2/binutils/prdbg.c", line 997


Object file is generated with "mcore-elf-gcc -gstabs+ -o <obj> -c <src>".

Error can be reproduced using following source:

/* begin of test.c */
typedef struct dummy {
  union {
    char Data[0];
    int Error;
  } D;
} dummy_t;
/* end of test.c */

If I delete the line 'int Error;' or change 'Data[0]' to e.g. 'Data[1]',
error disappears.


Shell dump:

# mcore-elf-gcc -gstabs+ -o test.o -c test.c
# mcore-elf-objdump -g test.o

test.o:     file format elf32-mcore-little
