GMP bug (?) - unable to build for ARM64 with assembly enabled

[Andreas Buff]

Hi Marco,

thanks to your help, its building fine now without --disable-assembly,  
but it crashes using it.

I am totally not into ASM, so forgive unqualified report(s).

Here is the backtrace:

* thread #8, queue = 'PEPAsyncSession.queue', stop reason =  
EXC_BAD_ACCESS (code=2, address=0x16fbcc000)
   * frame #0: 0x00000001019baf58 PEPObjCAdapterFramework`__gmpn_add_n + 144
     frame #1: 0x00000001019babe4 PEPObjCAdapterFramework`__gmpn_add + 68
     frame #2: 0x00000001019e756c  
PEPObjCAdapterFramework`__gmpn_toom2_sqr + 1020
     frame #3: 0x00000001019c8030 PEPObjCAdapterFramework`__gmpn_sqr + 144
     frame #4: 0x00000001019fe838 PEPObjCAdapterFramework`__gmpn_powm + 3416
     frame #5: 0x00000001019b5678 PEPObjCAdapterFramework`__gmpz_powm + 2432

Let me know if and how to provide more useful information if needed.

Thanks,
Andreas
