Dear Maintainer,
* What led up to the situation?
an update of the glibc
* What exactly did you do (or not do) that was effective (or ineffective)?
system calls stat/fstat/lstat cannot be virtualized
* an updated package is needed for trixie
the following code pt.c works on purelibc 1.0.9, it fails in 1.0.8
compile it:
gcc -o pt pt.c -l purelibc
