From 950bac27d63c1c2ac3a6ed867692d6a13f21feb3 Mon Sep 17 00:00:00 2001

Subject: [PATCH] sanitizer: Fix asan against glibc 2.34 [PR100114]
As mentioned in the PR, SIGSTKSZ is no longer a compile time constant in
glibc 2.34 and later, so
static const uptr kAltStackSize = SIGSTKSZ * 4;
needs dynamic initialization, but is used by a function called indirectly
from .preinit_array and therefore before the variable is constructed.
This results in using 0 size instead and all asan instrumented programs
die with:
==91==ERROR: AddressSanitizer failed to allocate 0x0 (0) bytes of SetAlternateSignalStack (error code: 22)
Here is a cherry-pick from upstream to fix this.
