>Description:
While building "x11/qt3-tools" on i386-8.0_BETA or i386-8.99.1, the
local tool 'uic' doesn't terminate, getting stuck in "fdclose" state.
Tail end of build on a system with MAKE_JOBS=5 (hw.ncpu +1):

This only occurs on systems with modular Xorg

The stuck 'uic' processes are unkillable, resisting even "-KILL".
Attaching 'ktruss' to one of them produces no output.

After rebooting, I restricted MAKE_JOBS to 1 for "qt3-tools". The build
gets stuck in the same place:
[...]
cd designer && /usr/pkg/bin/gmake -f Makefile
gmake[3]: Entering directory '/tmp/pkgsrc/x11/qt3-tools/work/qt-x11-free-3.3.8/tools/designer/designer'

Pressing Ctrl-T reports:

and 'top' reports:

So far the problem has manifested only on NetBSD-8.0_BETA or -8.99.1
with modular Xorg on i386. A test with NetBSD-7.1_STABLE-i386 and
modular Xorg is in progress.
I normally have no need of modular Xorg on amd64, but perhaps a test
setup can be arranged.

[stuck here]
The EACCESS result from "mmap()" suggests perhaps a PAX MPROTECT issue?
Setting:
paxctl +m ${WRKOBJDIR}/x11/qt3-tools/work/qt-x11-free-3.3.8/bin/uic
Allowed it to complete. Again, this is only needed when using modular
Xorg.
"qt4-tools" also builds a 'uic' tool but it does not exhibit any problem
with modular Xorg.

I've been trying to figure out how to automate this. Qt being what it is,
${WRKSRC}/tools/designer/uic/Makefile
is generated during the "configure" phase. A suitable SUBST arrangement
should do the trick, but my 'sed'-foo is weak. By itself, the following:
sed '/-o \$(TARGET)/a\
paxctl +m $(TARGET)
'
would add the necessary bits, but trying to cast it into something that
will satisfy both 'sed' and 'make' has been elusive so far. Something
like:
.if !empty(MACHINE_PLATFORM:MNetBSD-[89].*-i386)
SUBST_CLASSES+= mprotect
SUBST_STAGE.mprotect= post-configure
SUBST_MESSAGE.mprotect= Arrange for PAX MPROTECT flags
SUBST_FILES.mprotect= ${WRKSRC}/tools/designer/uic/Makefile
SUBST_SED.mprotect= -e '/-o \$$(TARGET)/a\
paxctl +m $(TARGET)
'
.endif
except the above "SUBST_SED" program won't satisfy both 'make' and 'sed'
at the same time. As I said, my 'sed'-foo is weak.
Another mechanism is to do something in a "post-configure:" target, but
again, getting 'sed' and 'make' to both be happy is being elusive.

I've just noticed the same issue with 'mplayer'. As with 'uic', it hangs
trying to "mmap()" the file descriptor previously obtained by opening
""/usr/pkg/lib/libGL.so.1".

Can you run it in GDB with a break point on mmap and figure out where

I instead hacked on "qt3-tools" to build 'uic' with debugging symbols
and ran it under 'gdb', since the behavior is the same as in mplayer

Looks like it's 'ld.elf_so' that's trying to do a RWX mapping?

Curiously, clearing the breakpoint and continuing the program under 'gdb'
allowed it to complete successfully.
Remaining in 'gdb' and running the program with each subsequent input
shown in the Makefile completes normally.
Resuming 'make build' phase normally causes 'uic' to hang in "fdclose"
on the next target it builds.

That would likely mean that the library has a text relocation or so. Can
you put it somewhere for download?

Find it here:
http://bobdbob.com/~jdbaker/nbsd-debug/i386nb9mod/libGL.so.1.2.0
Normally lives in "/usr/pkg/lib" on an i386-8.99.1 system.
Is it necessary to install shared-object libraries with mode a+x? That's
how everything in "/usr/pkg/lib" is set. Seems fraught to me.

Try rebuilding MesaLib with the attached patch please.

Done.

'mplayer' gets past this hurdle:

but ultimately fails due to text relocations and attempt to write-enable
a text segment. That's likely a topic for a different PR.
Modular Xorg no-longer hangs in "fdclose", but now segfaults. Excerpt
