Incompatibilities of userland 5.99.45 and 5.99.48

[Frank Wille <frank%phoenix.owl.de@localhost>]

These days I tried to update an ofppc and a sandpoint machine to 5.99.48.
Both fail with pkgsrc binaries compiled under 5.99.45, which worked before.

The segmentation fault always involves libpthread and __cxa_atexit().
This is a typical example:

Core was generated by `sqlite3'.
Program terminated with signal 11, Segmentation fault.
#0  0xefea7e4c in pthread_mutex_lock () from /usr/lib/libpthread.so.1
(gdb) bt
#0  0xefea7e4c in pthread_mutex_lock () from /usr/lib/libpthread.so.1
#1  0xefe2a62c in __cxa_atexit () from /usr/lib/libc.so.12
#2  0xefe2a708 in atexit () from /usr/lib/libc.so.12

#5  0xeffe2344 in _rtld_start () from /usr/libexec/ld.elf_so
Previous frame inner to this frame (corrupt stack?)

Did the interface of libpthread or libc change without incrementing the
so-version number?

Or is it caused by PPC-specific changes in the last weeks (like the
secure-plt stuff)?

This probably means I have to recompile all packages?
