+Set default pthread stack size to 256 KB
+
+This patch tries to fix various crashes for applications depending on libmilter
+by setting the stack size for pthreads to 256 KB. The default stack size for
+musl libc is set to 80 KB whereas glibc has it set to 8 MB. This causes problems
+when a large amount of memory is allocated on the stack.
+
+For example, opendkim allocates blocks of 64 KB multiple times, which causes
+libmilter (and therefore opendkim) to crash. For now, a stack size of 256 KB
+looks sufficient and makes opendkim stop crashing.
+
+Fixes https://bugs.alpinelinux.org/issues/6360
