GDB is more aggressive:

For Solaris, I believe it's been a while that the only maintenance
we've seen comes from you.  Which kind of makes you the de-facto
maintainer.  :-)  Since gcc obsoleted Solaris 9 years ago, and nobody
all these years stepped forward, I think we should be able to just drop
it.  I think you've proposed this in the past, even.  I very
much doubt anyone would step forward this time.
