cygwin (self-compiled) does not run (Re: cygwin patch&test workflow?)

Any further comments or help on this problem?
I tried once again to produce a fresh cygwin 1.7.0-62 src package compile, carefully cleared the environment from all non-cygwin-1.7 stuff (esp PATH), ran configure and make on the unmodified src, copied the dll to the cygwin 1.7 bin directory,
and still get the same crash (see below).
Can anyone reproduce this (with a setup.exe-installed src package, to be consistent)?

Since cygwin 1.7 (self-compiled) doesn't start, I tried cygwin 1.5 strace, invoking cygwin 1.7 bash (with --login -i).
This *did* work, so I don't think there's diagnostic value in it. If you yet want to see the 3.7 MB strace log (0.5 MB compressed),
Actually I'm not sure now it worked; I may have been mistaken by a confusion I had before, not really having involved 1.7 because I had loaded 1.5 previously; in a "working" case, uname reported 1.5, so this was bogus, sorry.
Running freshly from a Windows cmd.exe prompt, I get a significantly smaller trace:
