<https://www.openwall.com/lists/musl/2019/01/21/8> "This release makes improvements with respect to default thread stack size, including increasing the default from 80k to 128k, increasing the default guard size from 4k to 8k, and allowing the default to be increased via ELF headers so that programs that need larger stacks can be build without source-level changes, using just LDFLAGS. Insufficient stack size for AIO threads on kernels that don't honor the constant MINSIGSTKSZ is also fixed. The glob core has been rewritten to fix inability to see past searchable-but-unreadable path components, and to avoid excessive stack usage and unnecessary syscalls. The tsearch AVL tree implementation has also been rewritten for better size and performance. The math library adds more native single-instruction implementations for arm, s390x, powerpc, and x86_64. Various bugs are fixed, including several possible deadlocks, one of which was a new regression in 1.1.20." detailed release notes can be found in the WHATSNEW file: <http://git.musl-libc.org/cgit/musl/tree/WHATSNEW#n1989> Tested-by: Koen Vandeputte <koen.vandeputte@ncentric.com> Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
