Thanks Georg, but I can't on cygwin (see below).

I attach here the bt I get on cygwin. Do you see what I mean when I say
that I am always scared in a way or another by gdb on Windows? :(
When running LyX outside gdb I simply get:
Abort (core dumped)
Anyway, I can reproduce the crash on both linux and solaris.
All I have to do is replacing "#define SIZEOF_WCHAR_T 4" with
"#define SIZEOF_WCHAR_T 2" in src/config.h (after configuring)
and then "touch src/support/types.h" before "make".
Please attached find the bt's I get on linux and solaris. I use GCC 3.4.4
on cygwin, GCC 3.4.3 on solaris, and GCC 4.1.2 on linux (debian/testing).
I get the crash immediately at start on linux, but only after trying to
load a file (or even File->New) on cygwin and solaris (this must be
related to the GCC version).
The bt's on linux and solaris point to the same problem but I am lost
here as I am not able to interpret what is happening :(
