Package: strace
Severity: important
Hi,
I've noticed (and other people confirmed) that strace is broken for
kernels 2.6.13 or later on sparc. The breakage appears to be independent
of strace version. To illustrate the problem, I attached two files, both
containing a log of 'strace /bin/ls'. First one (log_2.6.12) was produced
on etch system with strace 4.5.8-1.2, running the kernel 2.6.12 from the
linux-image-2.6.12-1-sparc64 (version 2.6.12-10) package. There everything
works as expected. The other one (log_2.6.14) was obtained using the same
version of strace, but the running kernel is 2.6.14 from the sid
linux-image-2.6.14-1-sparc64 package (version 2.6.14-2). There strace
output is clearly broken and the command hangs in the end. Others have
confirmed, that the same behaviour is observed with the current strace
version in sid.
