Bernd Schmidt found/fixed this problem in uClibc: http://blackfin.uclinux.org/tracker/index.php?func=detail&aid=882&group_id=17&atid=141 Basically, the uClinux dist includes a few thread demos - thdm and bcdm - running them simultaneously sometimes causes bus errors.

Please retest, >everyone... This patch was made against our cvs, which has an older version of uClibc in it - this code was recently moved from internals.h to descr.h in the uclibc svn, but it still has the same problem

2005-05-20Finish up reverting NPTLEric Andersen
2005-05-20Back out nptl changes, which for now will be done in branches/uClibc-nptlEric Andersen
2005-05-14There were two versions of 'pthreadtypes.h' originally in uClibc. Also,"Steven J. Hill"
since we are going to support the two implementations of pthreads, we again need to instead create symbolic links to use the proper version of the file depending on the pthreads option chosen.
2005-05-14In order to accomodate usage of either pthreads implementation, we now"Steven J. Hill"
have to create symbolic links for 'semaphore.h' and 'pthread.h' which will point to the proper pthreads directory. When we finish getting NPTL working with uClibc, perhaps we can merge them, but a first glance at the differences between the two does not make that very likely.
2005-05-12Added new common include file for list primitives used by NPTL."Steven J. Hill"
2005-05-12Remove usage of 'hp-timing.h' header file which is for platforms with high"Steven J. Hill"
performance timers. If you want them included in the NPTL build, copy the header from glibc into the 'libc/sysdeps/linux/<ARCH>' of your choice and have fun.
2005-05-12Put the change log back in."Steven J. Hill"
2005-05-11More glibc backward compatibility cruft. Oh the horror!"Steven J. Hill"
