-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.
