1.7.7-1: troubleshooting "couldn't allocate heap, Win32 error 487"

[Casey Boettcher <cboettcher at gmail dot com>]

Hello,

I'm attempting to troubleshoot a problem that occurs when I boot
Windows 7 normally, but does not occur when I boot into Safe Mode.

The problem is this: when I run cygwin.bat, I receive the following
within the console (excerpted here, but full output is attached in
bash.out):

-----
      2 [main] bash 1264 C:\cygwin\bin\bash.exe: *** fatal error -

Running mintty.exe produces:

-----
Failed to fork child process: Resource temporarily unavailable.
DLL rebasing may be required. See 'rebaseall --help'.
-----

This same type of issue has been encountered before on the list, and
has been resolved by turning off services or killing processes that
are in the BLODA. I've killed off all the processes that I can, have
compared the list of services that are running in safe mode (with
Cygwin working) to the list of services outside of safe mode (without
Cygwin working) and have killed off the difference, but to no avail.

Rebaseall (no arguments, in Safe Mode) does nothing.

I've tried strace, but nothing in the output (attached as bash.strace)
seems to point to the culprit.

I've attached output from "cygcheck -r -s -v" as instructed on
http://www.cygwin.com/problems.html

Any advice on how to further diagnose/troubleshoot the issue would be
appreciated.

Casey
