3.0.7(0.338/5/3): Possible reference to Developer's instances of dev files in deployed build

["Wilfed Olaf Sulla via cygwin" <cygwin at cygwin dot com>]

Hi,

Cygwin is core dumping with the following message:

assertion "p >= path" failed: file "/home/corinna/src/cygwin/cygwin-3.0.7/cygwin-3.0.7-1.x86_64/src/newlib-cygwin/winsup/cygwin/path.cc", line 2916, function: int symlink_info::check(char*, const suffix_info*, fs_info&, path_conv_handle&)


To recreate this event:

shackleton:sulla:$ cd /cygdrive/
shackleton:sulla:$ ls -la


Build:

CYGWIN_NT-6.1 shackleton 3.0.7(0.338/5/3) 2019-04-30 18:08 x86_64 Cygwin
Windows 7 Professional Ver 6.1 Build 7601 Service Pack 1

-	Yes, it is an old machine that has been around for a while, but it
	does the job asked of it.


A similar event seems to have cropped up before, with a pair of patches
following:

	Re: winsup\cygwin\path.cc issues
	https://sourceware.org/ml/cygwin/2018-05/msg00315.html

	Cygwin: normalize_win32_path: Avoid buffer underruns
	https://sourceware.org/git/?p=newlib-cygwin.git;a=commitdiff;h=35998fc2fa6c

However I have not found any specific mention to the event described
above.


Background:

I came across the event while troubleshooting an install of Perl via
perlbrew that is throwing errors on the some Cygwin tests. The machine
is patched on a regular basis, but a stat on C:\cygwin64 comes up with:

	Birth: 2014-12-05

One of the perl install tests that failed seems like it could be
related, though I am not sure at this stage.


I have attached a copy of a stack trace, and a redacted cygcheck.out.

The following in the latter might be of relevance:

HKEY_CURRENT_USER\Software\Cygwin
HKEY_CURRENT_USER\Software\Cygwin\Installations
  (default) = '\??\C:\cygwin64'
HKEY_CURRENT_USER\Software\Cygwin\Program Options
HKEY_LOCAL_MACHINE\SOFTWARE\Cygwin
HKEY_LOCAL_MACHINE\SOFTWARE\Cygwin\Installations
  (default) = '\??\C:\cygwin64'
HKEY_LOCAL_MACHINE\SOFTWARE\Cygwin\Program Options
HKEY_LOCAL_MACHINE\SOFTWARE\Cygwin\setup
  (default) = 'C:\cygwin64'


P.S.
Many thanks to all concerned for their efforts over the years.
