I hope not. :) For starters, I don't think my first question has
anything to do with the FAQs you're pointing out.

Yes. As I mentioned above, I have actually read those. My second
question is whether the crashes I am seeing are likely to be a
consequence of this.

Thanks for pointing this one out. This may answer my last two questions,
and I'd in fact seen the FAQ entry, but wrote it off to a serious case
of impedance mismatch. I found how-cygtls-works.txt at
http://cygwin.com/cgi-bin/cvsweb.cgi/~checkout~/src/winsup/cygwin/how-cygtls-works.txt?rev=1.1&content-type=text/plain&cvsroot=src
and read it. Unfortunately it is unclear how a discussion of the NT_TIB
structure from <w32api/winnt.h> relates to my question. The other
reference, winsuite/testsuite/cygload, appears to be emptry:
http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/testsuite/cygload/?cvsroot=src
I'll now try to get this snippet also mentioned in the FAQ to work:
HMODULE h = LoadLibrary("cygwin1.dll");
void (*init)() = GetProcAddress(h, "cygwin_dll_init");
init();
Cheers,
Christian
