Bug #: 14931
Summary: GDB fails to read minsyms if debug info reading fails.
Product: gdb
Version: 7.0
Status: NEW
Severity: normal
Priority: P2
Component: symtab
AssignedTo: unassigned@sourceware.org
ReportedBy: palves@redhat.com
Classification: Unclassified
Trying to check gdb's behavior in a previous release, I did:
$ ~/gdb/7_0/build/gdb/gdb -nx ./gdb/gdb

Reading symbols from /home/pedro/gdb/mygit/build/gdb/gdb...Dwarf Error: wrong
version in compilation unit header (is 4, should be 2) [in module
/home/pedro/gdb/mygit/build/gdb/gdb]
(gdb)
The old GDB didn't understand dwarf 4, so it bailed out, but it also didn't
load the minsyms, while it could. I think it should:
(gdb) b main
No symbol table is loaded. Use the "file" command.
Make breakpoint pending on future shared library load? (y or [n])
$ nm -A ./gdb/gdb | grep "T main$"
./gdb/gdb:0000000000457b4c T main
I haven't tried current mainline's behavior.
