Summary: Can't reserve space for heap

Initial Comment:
When attempting to run rxvt, I get the following and
rxvt, of course, doesn't execute:

m.AllocationBase 0x0, m.BaseAddress 0x715B0000,
m.RegionSize 0x160000, m.State 0x10000
C:\msys\1.0\bin\rxvt.exe: *** Couldn't reserve space
for cygwin's heap (0x715B0000 <0xF10000>) in child,
Win32 error 6

Win32 erorr 6 appears to be an invalid handle. I'm
happy to attempt to look in the source code, if only I
had a clue where to start. I'm using the Current
release, downloaded about two days ago. Cygwin is
installed, but not present in PATH.

I've perused the winsup/cygwin/cygheap.cc source code, and
nothing seems to immediately spring to forefront as an
obvious reason why the cygwin heap allocation fails.

However, there's a glaring problem in that code: another
call to a Win32 method occurs overwriting GetLastError()
(the "%E" format spec). So the actual reason why the call is
failing is masked.

I can't recompile, for obvious reasons, to examine the bug
further.

No CYGWIN environment variable set, PATH is set to the
minimal path possible
(\WINNT\SYSTEM32;\WINNT;\WINNT\SYSTEM32\Wbem).

Do you have the CYGWIN environment variable set?  I seem to
remember something from long past about a problem from the
contents of the CYGWIN variable that could cause this.
