Details:

Hi,

With a recent version of the development sources
whenever I try to run standalone programs embedding the interpretr, e.g.
examples/embedded.cc, I get a segfault.



$ hg id
1e8f8900a041 tip @
$ mkoctfile -g --link-stand-alone embedded.cc -o embedded
$ ./embedded


This is the result of running the program in the interpreter
and the backtrace of the segfault.



GCD of [10, 15] is 5

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: 13 at address: 0x0000000000000000
0x00000001024e4b1e in std::_Rb_tree_increment ()
(gdb) bt
#0  0x00000001024e4b1e in std::_Rb_tree_increment ()
#1  0x000000010036e7c0 in symbol_table::erase_subfunctions_in_scope ()
(gdb) 



last time this was working was a couple of weeks ago.

c.
