Linuxthreads fails tests with current glibc 2.2 version

Linuxthreads fails tests with current glibc 2.2 version

[Andreas Jaeger]

Just a short notice:
The linuxthreads test ex1, ex2, ex3, ex4, ex5 and ex6 fail for me in
on i686-linux.

No time to investigate why,

and also rt/tst-aio* and elf/resolvfail fail (all programs use
linuxthreads).


configured with: 

/cvs/libc/configure --prefix=/usr/src/test/glibc-2.2 \
--enable-add-ons --disable-profile --without-cvs --enable-kernel=2.2.0 \
--with-headers=/usr/src/linux-2.3.34-2/include

on i686-linux, running Linux 2.2.13 but with headers from 2.3.34pre2,
gcc 2.95.2.  If I compile with headers from 2.2.13 everything seems to
work.

Here's an output from gdb on elf/resolvfail:
Program received signal SIGSEGV, Segmentation fault.
0x400de728 in __new_getrlimit (resource=RLIMIT_STACK, rlimits=0xbffff654)

Could somebody doublecheck the recent linuxthreads and getrlimit
changes, please?

I'm currently lost - and won't have time to check this myself today or
tomorrow,

Neither fails for me.

They only fail with kernel headers from 2.3.33 or 2.3.34pre2 and an
installed 2.2.13 kernel.

It works with headers from 2.2.13.

This might be a bug in my kernel.

OK, I'm running 2.3.33.  But it sounds rather like a problem in the
rlimit stuff.
