Hello!
I had used WML (offline HTML generator, Perl-based, version 2.0.9,
<http://thewml.org>) happily under Cygwin with no problems whatsoever.
Then along came some system-upgrade[1], and boom, eperl (a
subcomponent of WML) just dies when trying to open a file. (That
means, e.g. "eperl --help" produces some output, so the program
doesn't *completely* just die) The other WML-components still work
just fine.
I'm no expert on debugging this kind of things, but I ./configure'd
WML with --enable-debug and was able to get this from gdb:
###
$ gdb eperl
This GDB was configured as "i686-pc-cygwin"...
Minimal symbols from eperl.exe...(no debugging symbols found)...
[I think that's strange, as I *did* say --enable-debug]
(gdb) run README
[this just proves the point that the actual file doesn't matter]
Starting program: /cygdrive/d/wosc/install/Cygwin/wml-2.0.9/wml_backend/p3_eperl/eperl.exe README

[this sequence keeps repeating over and over]

Does anybody have an idea what I might be looking at here, and what I
could do about it?
Thanks for your help,
Wolfgang
[1] from what I know, it might have been core cygwin.dll 1.5-3 to -4
or perl-5.8.0 to -5.8.2, but that's just me guessing, because
reverting to the old versions doesn't solve the problem.
This just proves the saying "Never touch a running system"... :-(
Current Versions are cygwin-1.5.7-1 and perl-5.8.2-1.
