--- Comment #2 from Florian Weimer <fw at gcc dot gnu.org> ---
The reason for this change in glibc 2.34 is that the size of the context
information pushed by the kernel has increased by about an order of magnitu=
de
over the last decade.

Missing size check in sigaltstack=20

x86: MINSIGSTKSZ too small for AVX-512F support=20
https://sourceware.org/bugzilla/show_bug.cgi?id=3D20305

Small signal stacks needed to be allocated at run time, using the
kernel-supplied size plus the extra part that the application needs.=
