- Subject: [commit] Fix crash of gdb save-index on a STABS file
Hi,
checked in, index saving functions crashed on NULL psymtabs_addrmap.
Running gdb/testsuite/gdb.stabs/gdb11479.exp ...
-gdb compile failed, gdb/cc-with-index.sh: line 107: 3487 Segmentation fault (core dumped) $GDB --batch-silent -nx -ex "file $output_file" -ex "save gdb-index $output_dir"

No regressions on {x86_64,x86_64-m32,i686}-fedora15-linux-gnu.
There are some concerns what is a file uses both DWARF and STABS, it may
possibly currently have a regression with .gdb_index. But that is unrelated
to this patch.
Thanks,
Jan
