Description Andrew Cagney 2007-08-30 20:22:39 UTC
Consider:

GLOBAL(large_global_at_small_global)
GLOBAL(small_global_at_large_global)
        STORE(REG0,REG0)
        NO_OP
        SIZE(small_global_at_large_global)
        NO_OP
        SIZE(large_global_at_small_global)

it appears large_global_at_small_global is returned, but I suspect the selection
is unstable given:

$ nm -p -S frysk-core/frysk/pkglibdir/funit-symbols| grep -e
small_global_at_large_global -e large_global_at_small_global
080483ca 00000004 T large_global_at_small_global
080483ca 00000003 T small_global_at_large_global

it's choosing the first one.

Comment 1 Roland McGrath 2007-09-11 19:13:41 UTC
You are right that it chooses the first one in the symbol table.
I think choosing the smaller one is the better behavior.

Comment 2 Roland McGrath 2007-09-11 19:23:17 UTC
Fixed upstream.

Comment 3 Roland McGrath 2007-10-16 09:57:54 UTC
This issue should be resolved by elfutils-0.130.  If there is still a problem,
reopen or file a new bug report with complete test case details.
