The issue has been resolved in gmp-6.3.0 for M silicon. I am how looking at: https://lists.rtems.org/pipermail/users/2023-October/068894.html and the crash is in a GMP call via MPFR. This is on Intel silicon on Ventura. I have just run `make check` on the RSB build of GMP and it is not great: ============================================================================ Testsuite summary for GNU MP 6.3.0 ============================================================================ # TOTAL: 53 # PASS: 10 # SKIP: 1 # XFAIL: 0 # FAIL: 42 # XPASS: 0 # ERROR: 0 > In any case I ran make check, so at least for all the builtin tests, there is > no > issues.

Yes. An example of the usage can be seen in the above crash building the libgcc div3c module. The back trace is: thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0xd5) * frame #0: 0x.. frame #1: 0x.. cc1`__gmpn_bc_set_str + 1370 frame #2: 0x.. cc1`parsed_string_to_mpfr() at strtofr.c:555:20 [opt] frame #3: 0x.. cc1`mpfr_strtofr() at strtofr.c:965:13 [opt] frame #4: 0x.. cc1`real_from_string(r=0x00007ff7bfefb350, str="1.79769313486231570814527423731704357e+308") at real.cc:2152:17 [opt] > Why would you cross-compile these libraries? Sorry if I was not clear. Those libraries are not being cross-compiled, it things like libgcc that are and in this case of the crash posted here the failure appears when building that code.
