Photon post-mortem debug, WD SIGSEGV's

I’ve got a 2+ MB core dump from a gui application that I need
to debug with wd. The app was compiled/linked -g2d.

When I try to load the core dump into wd to debug it, wd dies
with a SEGV at E5:65B.

I’ve debugged core dumps before, but have never seen this.

Photon 1.14, QNX 4.25, watcom 10.6

Ideas?

does dmpinfo indicate that it is a valid core file produced?
you did the right thing by compiling and linking with the -g2d switch.

but as to why wd failed i do not know… if you can compress and upload the
dmp i could take a look.
