It seems that the latest release of gdb doesn't quite get debug info
right when reading apps compiled with the experimental gcc-4.5
package. It's a lot closer than the old gdb was able to get, but
reported line numbers are usually off by 3-5 lines and breakpoints are
similarly affected.Huh. Seems to have been a fluke... now that I've built a gdb-7.3 from
scratch, both it and the cygwin version work equally flawlessly. The
only things that have changed are that I rebased my system because the
gdb build was spawning fork failures left and right, and I recompiled
the binary (maybe with different flags? the flags I used before were in
an emacs session which I had to close to rebase). I don't know why the
former would affect anything, and I'll remain skeptical of the latter
unless I stumble across another magic combo of "bad" compiler flags (I
wasn't doing anything crazy or unusual in that area).
Is there some obvious reason I shouldn't expect this to work, and have
other people seen similar problems? If the answers are "no" and "no"
I'll start trying to isolate a small test case, and meanwhile I'm
building a gdb from scratch which I'll report back on.
Sorry for cluttering up the list with this.
