Is this somthing special about cygwin or is our autoconf test broken?
The former, I think.
Or not, maybe, see below.
This is what I get when comparing cygwin and native windows
configuration:
$ diff -up build-cygwin/config.h build-win32/config.h | grep -B1 STD_STRING
/* std::string uses copy-on-write */
-#define STD_STRING_USES_COW 1
+/* #undef STD_STRING_USES_COW */
So, cygwin is using COW in the std::string implementation...
I hacked config.h by undefining STD_STRING_USES_COW and recompiled.
LyX does not crash anymore and works fine, seemingly...
