Yep, but that's pretty much the same in every cygwin app, so I would expect
any bugs in it to manifest more widely.

Fair enough, I was just thinking that the other main thing to happen before
startup is .init c-tors running.

Sorry, I haven't been clear; that was only relevant to the theoretical case
that you were invoking the linker directly. Since you're using the gcc
driver, nonoe of this should be necessary.

Hmmm, or perhaps it's a real error that affects one of your target programs
differently than the other.

That's STATUS_DLL_NOT_FOUND. Interesting. I wonder if something's
interfering with dll loading?

And those are STATUS_ACCESS_VIOLATION. Odd. Are you, by any chance,
running any of:
Sonic Solutions burning software containing DLA component
Norton/MacAffee/Symantec antivirus or antispyware
Logitech webcam software with "Logitech process monitor" service
Kerio, Agnitum or ZoneAlarm Personal Firewall
Iolo System Mechanic/AntiVirus/Firewall
LanDesk
Windows Defender
Embassy Trust Suite fingerprint reader software wxvault.dll
