I checked again and it doesn't crash on macOS, however the original
non-reduced patch does reliably crash. It seems it requires a different
reduced version for macOS.

From 0.48, macOS 10.11:

pd(4254,0x7fff79118000) malloc: *** error for object 0x7fc3b2096208: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
Pd: signal 6
gui socket 4 - closing audio...
