I've built Sage 64-bit on OpenSolaris but it crashes at startup. I've run gdb
and find the bit of code that's causing the crash is this.
./devel/sage-main/sage/symbolic/function.cpp
/* "sage/symbolic/function.pyx":109
* raise ValueError, real_fname + " parameter must be callable"
*
* if not self._is_registered(): # <<<<<<<<<<<<<<
* self._register_function()
*
*/
commenting out the next few lines of
./devel/sage-main/sage/symbolic/function.cpp
/* __pyx_t_2 = ((struct __pyx_vtabstruct_4sage_8symbolic_8function_Function
*)((struct __pyx_obj_4sage_8symbolic_8function_Function
*)__pyx_v_self)->__pyx_vtab)->_is_registered(((struct
__pyx_obj_4sage_8symbolic_8function_Function *)__pyx_v_self)); if
(unlikely(!__pyx_t_2)) {__pyx_filename = __pyx_f[1]; __pyx_lineno = 109;
__pyx_clineno = __LINE__; goto __pyx_L1_error;}
__Pyx_GOTREF(__pyx_t_2);
__pyx_t_6 = __Pyx_PyObject_IsTrue(__pyx_t_2); if (unlikely(__pyx_t_6 < 0))
{__pyx_filename = __pyx_f[1]; __pyx_lineno = 109; __pyx_clineno = __LINE__; goto
__pyx_L1_error;}
__Pyx_DECREF(__pyx_t_2); __pyx_t_2 = 0;
__pyx_t_5 = (!__pyx_t_6);
*/
allows Sage to run. It's not 100% stable, but much better than before.
This comes from:
./devel/sage-main/build/sage/symbolic/function.pyx (around line 109)
#
###### if not self._is_registered():
###### self._register_function()
######
###### global sfunction_serial_dict
###### sfunction_serial_dict[self._serial] = self
#
Can anyone see if there might be something wrong with this code, which is
causing Sage to segfault?
I've not tied it down to a specific line yet, but just removed everything under
the 'if' statement.
Why when I edit the .pyx file and type
./sage -b
does it not rebuild the C++ code? I ended up having to edit the C++ manually to
comment out the lines causing the crash.

Q: Why is top-posting such a bad thing?
