I just noticed that there is a regression in glibc on alpha with version 2.34 or later.
Looking at the build logs for Debian's 2.34-8 [1], 2.35-4 [2] and 2.36-4 [3], it's obvious
there is something wrong given the many "Segmentation Fault" errors.
This regression was introduced by the following commit:
6c57d320484988e87e446e2e60ce42816bf51d53 is the first bad commit
commit 6c57d320484988e87e446e2e60ce42816bf51d53

sysconf: Add _SC_MINSIGSTKSZ/_SC_SIGSTKSZ [BZ #20305]
Add _SC_MINSIGSTKSZ for the minimum signal stack size derived from
AT_MINSIGSTKSZ, which is the minimum number of bytes of free stack
space required in order to gurantee successful, non-nested handling
of a single signal whose handler is an empty function, and _SC_SIGSTKSZ
which is the suggested minimum number of bytes of stack space required
for a signal stack.
FWIW, it does not seem to affect alpha systems with a higher baseline such as EV67.
