- Subject: [patch] .gdb_index: Fix Ada regression
Hi,
on a system with libraries using .gdb_index all the Ada testcases FAIL:
Running ./gdb.ada/print_pc.exp ...
FAIL: gdb.ada/print_pc.exp: start inferior (GDB internal error)
FAIL: gdb.ada/print_pc.exp: p /x $pc
dwarf2read.c:2374: internal-error: map_ada_symtabs called via index method
FAIl is on Fedora 14 snapshot using gcc-debuginfo-4.5.1-3.fc14.x86_64 file:
/usr/lib/debug/lib64/libgcc_s-4.5.1-20100907.so.1.debug
The regressions get fixed on x86_64-fedora14snapshot-linux-gnu by the attached
patch. No regressions on {x86_64,x86_64-m32,i686}-fedora14snapshot-linux-gnu.
During my tests with `set language ada' I could not lookup non-Ada symbols
anyway so I believe the patch is OK but sure it needs an Ada-wise review.
Thanks,
Jan
