Starting with glibc 2.34 the SIGSTKSZ macro is not a value anymore but calls sysconf(_SC_SIGSTKSZ) instead. This means that kSigStackSize needs to be initialized via a static initializer. However it appears that something is invoking pthread_create() before static initializers have run, so kSigStackSize is zero when entering the interposer and we fail to allocate the alternate signal stack. We should fix this to ensure the interposer is working as expected on distros that have already rolled out glibc 2.34.
