Hi David
Make sure that you compile Vim with "-g -O0" to enable debug and
disable optimisations which can hinder debugging. Then make sure
that you're not using a strip version of Vim ("make install" strips Vim
by default, i.e. removed debug symbols).
This should do it:

Rebuild Vim. Then you can run Vim with gdb with a breakpoint
when Vim gives E341:
$ cd vim/src
$ grep -n E341 *c
misc2.c:902: EMSGN(_("E341: Internal error: lalloc(%ld, )"), size);
$ gdb --args ./vim -f -g
(gdb) br misc2.c:902
Breakpoint 1 at 0x4eb006: file misc2.c, line 902.
(gdb) run
Then when Vim hits the breakpoint, you can type gdb command "bt"
to get a backtrace.
