Description Chris Friesen 2010-05-31 19:06:47 UTC
This is a third-party bug report.

It appears that on RHEL 5.5 a pthread mutex in shared memory cannot be used by a
combination of 32-bit and 64-bit apps.

I realize that posix doesn't guarantee that this will work since they are
technically different programming models, but it seems like a useful capability
to have.

Comment 2 Ulrich Drepper 2010-06-15 02:26:31 UTC
This is no bug and there is no way to accommodate such uses because of binary
compatiblity with data structures introduced in LinuxThreads a long, long time ago.
