graphics/hugin from pkgsrc-2023Q1 startup crash on netbsd-9 amd64

[Paul Ripke <stix%stix.id.au@localhost>]

Wondering if anyone has managed to use hugin recently?

I got this on startup:

ERROR: 13:06:07.299255 (/home/tmp/pkgwrk/graphics/hugin/work/hugin-2022.0.0/src/hugin1/hugin/GLViewer.cpp:134) SetUpContext(): Error initialising GLEW: Unknown error.

followed by SIGILL from infinite recursion until it runs out of stack.

I've found refs to using libepoxy to fix GLEW issues, and found and patched:
https://sourceforge.net/p/hugin/hugin/ci/4a3fe139b64b06f95c80db9d24a1a5a35e7abb60/

It now seems to get further along, rendering windows, etc, and then
Aborts with no meaningful error. gdb backtrace from a debug build
isn't that helpful, since it appears to trap SEGV:

Program terminated with signal SIGABRT, Aborted.

The backtrace from its xml dump is only slightly more meaningful:

<frame level="0" offset="0" address="0x7156e946f0ed" module="0x7156e946f0ed &lt;_Z14GenerateReportN13wxDebugReport7ContextE+0x111&gt; at /usr/pkg/lib/libhuginbasewx.so.0.0"/>

Running under gdb, I get the far more meaningful:

Has anyone managed to get past this? Or should I whack on it some more?
