-----------------------------+----------------------------------------------
On bsd.math (hence, Darwin), there is a problem with the GP executable
when building Sage (or: only the pari/gp spkg) with SAGE_DEBUG=yes.
As Jeroen found, a crash occurs as follows:
{{{
$ ./sage --gp
? factor(-70665476079756004438844153774)
}}}
With gdb, one then gets
{{{
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: 13 at address: 0x0000000000000000
0x00007fff8a66cfc1 in dyld_stub_binder ()
(gdb) bt
#0 0x00007fff8a66cfc1 in dyld_stub_binder ()
#1 0x000000010040e398 in stub helpers ()
}}}
A smaller testcase is `? factor(10356613*10694706299664611221)`
According to Jeroen, the problem vanishes with Apple's gcc.
