Is there a serious NPTL problem with sarge?
a colleague observed crashes in some heavily multi-threaded Python
applications. He is running Debian sarge with stock kernel
2.6.8-2-686. Using LD_ASSUME_KERNEL "fixes" the crash, so it seems
to be an NPTL issue. (Maybe stupid) questions:
- Is it relevant, whether Python is compiled on a system with 2.6
or 2.4 kernel? If so, how can I find out on which kernel the
Debian package has been built?

linuxthreads and NPTL are not binary-compatible. So in fact, an
installation with NPTL should be considered as a different
operating system, and you cannot expect to move binaries from
one operating system to another. Instead, you have to recompile
- Is the Debian stock 2.4 kernel patched to be compatible with
NPTL? If not, isn't there a problem for some multi-threaded
applications to switch between 2.4 and 2.6? (Note: AFAIK, RH,
Mdk, and SuSE use some patch, at least Fedora seems to have
"nptl" in the 2.4 kernel version number.)
Thanks in advance for any clarification.
