file_wordexp_new:wordexp(..) failures on cygwin

[jwernerny -2-]

file_wordexp_new:wordexp(..) seems to be failing on Cygwin in svn version 4155.

The output below shows debug information (after applying the patch in ticket 775 which solves a NULL ptr issue this issue contributes to).

Oops, make that "Patch from ticket 774

Hi Jwernerny,

can you paste the output of "bt full" command of gdb after setting

<debug name="segv" level="2"/>

in your navit.xml? (this will start an interactive gdb session on crash)

I did an SVN update, so this may not be too useful.... BUT, before that I did find the cause of the segv from the ticket. It's another NULL Ptr in map_destroy(..) in map.c.

$navit -d 100
TODO Verbose option is set to `100'
navit:file_wordexp_new:wordexp('/cygdrive/c/Documents and Settings/JWerner8/.navit/bookmark.txt') returned 5
navit:map_rect_get_item:map.c:320 assertion failed:mr != ((void *)0)
Aborted (core dumped)

The root cause of this seems to be that wordexp(..) on my cygwin install is broken. I even went as far as both writing a test program and downloading one (from lassauge.free.fr/cygwin/release/X11/celestia/test-wordexp.c) and they fail. wordexp(..) always returns 5 (WRDE_SYNTAX).

Can anybody please check this bug on cygwin?
