Yes, I run nightly build without --enable-64-bit-bfd here to test such bugs. The goal of my proposal was to catch most of the bugs already by the submitter. We cannot want from all submitters to test too many combinations (I do 3*17 = 46 runs; it equals a bit less due to some limitations). So we should choose some best single catch-almost-all configuration. While there are countercases I believe >90% of bugs get more caught by --enable-targets=all --enable-64-bit-bfd than by any other settings. After I know submitters run --enable-targets=all themselves I probably start also runs without --enable-targets=all to test the other case, also I would start new runs running -lmcheck. > I'm not in favour of this patch.

I find the largest disadvantage that after switching to development=false for the release the srctree becomes "untested". Even -lmcheck may hide some bugs. But there is also the pre-release gdb-x.y.90.z phase to catch those bugs. I just find current regressions happenning almost daily without this patch to be too boring. Thanks, Jan
