File permissions appear ok as far as I can tell. The 'strace' output
seems consistent with no permission problems; I'm able to execute all
commands, cygwin1.dll is found, and things run for a short while
before dying.
'strace sh.exe' looks like any other command I try:
...
564 105230 [main] bash 3892 cygheap_user::ontherange: what 2, pw 0xA0510C8
224 105454 [main] bash 3892 cygheap_user::ontherange: HOME is already in the environment /cygdrive/h
756 106210 [main] bash 3892 sigproc_init: process/signal handling enabled(1001)
365 106575 [main] bash 3892 __cygwin_lock_lock: threadcount 1. not locking
304 106879 [main] bash 3892 __cygwin_lock_unlock: threadcount 1. not unlocking
and I'm back to the Windows command prompt at this point. I thought
maybe there could be something odd in my environment, but deleting all
entries has no effect: I still see the exact same behavior with an
environment that consists, in its entirety, of "PATH=.".
By hunting around on the internet, I was able to find some old cygwin
versions to test. With an old version of 'mount', I get normal output
with the 1.5.5-1 version of cygwin1.dll, but 1.5.6-1 behaves the same
as 1.5.11-1 and 1.5.12-1 (no output, exits following sigproc_init).
I see that the 1.5.6-1 release changed signal processing which seems
suggestive given that the last substantive output of 'strace' comes
when signal handling is enabled.
