I get a core dump instantly when starting up the current CVS lyx.
I have tracked down the problem to language.C's LangInit::initL() and the
line:
if (languages.find(lyxrc.default_language) == languages.end()) {
The problem lies with lyxrc.default_language. Modifying the source slightly
to:
std::cerr << "got to here 2" << std::endl;
std::cerr << "lyxrc.default_language " << lyxrc.default_language <<
std::endl;
if (languages.find(lyxrc.default_language) == languages.end()) {
gdb is not much help:
(gdb) r
Starting program: /usr/users/aleem/OTHERS_CODE/lyx/devel/src/lyx
got to here 1
got to here 2
lyxrc.default_language Memory fault(coredump)
But dbx does better:
(dbx) r
got to here 1
got to here 2
lyxrc.default_language signal Segmentation fault at

First, can someone explain the last few lines of language.C:
static
LangInit langinit;
bool LangInit::init = false;
Commenting them out allowed lyx to start, but loading the first document
causes a similar problem:
(gdb) r

Any ideas?
