The others rely on some of the recent restructuring+cleanup in musl, which hopefully reaches us soon :). For now just bump the default sizes.

Subject: [PATCH 3/4] increase default thread stack/guard size
|
|
|
|
stack size default is increased from 80k to 128k. this coincides with
|
|
Linux's hard-coded default stack for the main thread (128k is
|
|
initially committed; growth beyond that up to ulimit is contingent on
|
|
additional allocation succeeding) and GNU ld's default PT_GNU_STACK
|
|
size for FDPIC, at least on sh.
|
|
|
|
guard size default is increased from 4k to 8k to reduce the risk of
|
|
guard page jumping on overflow, since use of just over 4k of stack is
|
|
common (PATH_MAX buffers, etc.).
