Old implementation of realpath allocates a PATH_MAX using alloca for
each symlink in the path, leading to MAXSYMLINKS times PATH_MAX
maximum stack usage.
The test create a symlink with __eloop_threshold() loops and creates
a thread with minimum stack size (obtained through
support_small_stack_thre
This is an updated version from previous version synced with more
recent gnulib version b29d62dfa. It also contains a testscase for
the BZ #26421 and a fix to avoid a regression for BZ #22786.
