I get a core dump when trying to build gcc from the 4.0 release branch on
sparc-sun-solaris2.8 with the 2.15 binutils for as and ld.
The core dump is in the command
stage1/xgcc -Bstage1/ -B/u/jbuck/cvs.sol2/4_0_branch/sparc-sun-solaris2.8/bin/
-g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros
-Wold-style-definition -DHAVE_CONFIG_H -DGENERATOR_FILE -o

build/varray.o ../build-sparc-sun-solaris2.8/libiberty/libiberty.a -lm
collect2: ld terminated with signal 11 [Segmentation Fault], core dumped
The immediate cause of the crash is a null pointer dereference in
elf_sort_symbol:
#0 elf_sort_symbol (arg1=0x0, arg2=0xf7700)
at ../../binutils-2.15/bfd/elflink.c:2698
2698 vdiff = h1->root.u.def.value - h2->root.u.def.value;
(gdb) p h1
$1 = (struct elf_link_hash_entry *) 0x0
(gdb) p h2
$2 = (struct elf_link_hash_entry *) 0xf7700
The full backtrace is
