Hello,

I'm having a strange problem with tags in vim 7.1 that I've just installed.
My Cygwin version is 1.5.25-14.

I'm experimenting in directory c:/temp where I have a source file 
"test.c" and a tag file "tagfile" (see below).
I also set environment variable EXINIT as "set tags=tagfile".

File test.c :
------------------------

int my_function (int aaa)
{
}

------------------------

Depending on how the path to the source file is written in my tagfile, 
the command "vim -t my_function" executes differently :

*** Case (1)
tagfile:
------------------------
my_function    $TESTDIR/test.c    /^int my_function (int aaa)$/
------------------------
Environment variable TESTDIR is defined as "c:/temp".
Command "vim -t my_function" brings vim that reports:
------------------------
"/cygdrive/c/Temp/tes#" [New File]
E434: Can't find tag pattern
------------------------

*** Case (2)
tagfile:
------------------------
my_function    c:/temp/test.c    /^int my_function (int aaa)$/
------------------------
Command "vim -t my_function" CRASHES vim (segmentation fault) ....

*** Case (3)
tagfile:
------------------------
my_function    /cygdrive/c/temp/test.c    /^int my_function (int aaa)$/
------------------------
Only here the command "vim -t my_function" correctly loads test.c and 
finds the tag.


Is it a known problem?
Is there any cure for cases (1) and (2) ?
Is there a workaround?

Thank you,
Alex
