weird hangs in current (ghc, gnucash)

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

I've just updated my kernel from 10.99.10 to 10.99.10 (~ Oct 11 to Oct
20) to test the rge(4) changes, and started a bulk build, and the
packages using ghc seem to wait for something and make no progress.

In one of my sandboxes there is a hs-data-array-byte build but it's not
doing anything.

The log stops at:

===> Creating toolchain wrappers for hs-data-array-byte-0.1.0.1nb2
===> Configuring for hs-data-array-byte-0.1.0.1nb2
=> Checking for portability problems in extracted files
[1 of 2] Compiling Main             ( Setup.hs, Setup.o )

From ps:

pbulk   26131  0.0  0.1 1073923564  140684 ?      Il    8:23PM 0:00.23 /usr/pkg/lib/ghc-9.4.7/bin/./ghc-9.4.7 -B/usr/pkg/lib/ghc-9.4.7/lib -package-env - --make Setup -dynamic 

(btw, that is a really huge process size?!)

Attaching with gdb shows me:

(gdb)

I see one other new weird behaviour on that machine - gnucash doesn't
finish starting up.

Has anyone else similar problems with latest -current?
