The bug which caused a segfault in location list support is no longer
present. You may have found a new bug; if so, please provide a
testcase and backtrace.
The test case is the gnat1 built from the current tree, but that isn't
necessarily all that useful ...
I rebuilt with stabs to work around this previously. That's how I found
out that the code generation problem was in loop optimization.
But I don't understand why this suddenly started happening: gdb was
quite reliable for months and the only thing that changed was GCC, so
I think some recent change in dwarf2 output is causing problems.
