cmake core-dumps during libobjc2 build on 7.9/i386

Hi!

I updated to 7.9.
Previously I did run 7.7 without the reported issue. I did a full 
upgrade to 7.8, including pkg_add, but did not test. So the upgrade is 
smooth, but I did not test builds in intermediate 7.8

rohan$ cd Build/
rohan$ cmake ..
-- The C compiler identification is Clang 19.1.7
-- The ASM compiler identification is Clang with GNU-like command-line
-- Found assembler: /usr/bin/cc
-- The CXX compiler identification is Clang 19.1.7
-- Detecting C compiler ABI info
Illegal instruction (core dumped)


what exactly is core-dumping? I see no core dump.
