The automatic tests for a PR failed for a target that I could not test myself: 32-bit build on Darwin_64_32.

Testing attach_detach
timelimit -t 10 ./generated/osx/debug/32/attach_detach
attach_detach(32762,0xb0103000) malloc: *** error for object 0x10000000: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
make[2]: *** [generated/osx/debug/32/attach_detach.done] Error 134
make[1]: *** [test/thread/.run] Error 2
make: *** [unittest-debug] Error 2
How can I reproduce the issue perhaps on my Ubuntu-based 64-bit laptop? I'm hoping that the problem will be obvious if I can build a 32-bit target and "set a breakpoint in malloc_error_break to debug".
I tried to build a 32-bit dmd on my system but failed with dependency issues. Is the following right way?
$ MODEL=32 make -f posix.mak -j8 AUTO_BOOTSTRAP=1
