Title: Crashes by VRML output when current directory is not writable.
Submitter: IKEDA Soji

Subsys: Dot
Version: 2.20.3
System: *-*-
Severity: major

o current working directory is not writable by user,
o output filename is not specified (using -o option) and
o output format is specified as VRML (-Tvrml),
dot crashes with SEGFAULT.

I suppose this is because the path of node*.png is given by that of output file name in plugins/gd/gvrender_gd_vrml.c:nodefilename().

cd /a/directory/unwritable/by/me
dot -Tvrml > /tmp/dest.vrml
