>Synopsis: Segmentation fault in __powerpc_read_tcb on G3
>Category: powerpc
>Environment:
System : OpenBSD 5.2
Details : OpenBSD 5.2-beta (GENERIC) #226: Sun Jul 15 02:13:32 MDT
2012
[email protected]:/usr/src/sys/arch/macppc/compile/GENERIC
Architecture: OpenBSD.macppc
Machine : macppc
>Description:
All threaded programs end up segfaulting on my B&W G3 (Rev 1).
This makes most ports unusable, since a lot of ports use threads
(or a library that links to them), i.e: they almost always crash
at start-up.
This looks specific to the G3 processor, as I'm surprised it
hasn't been reported yet.
Please see the output of base gdb [1] and gdb-7.4.1 from
ports [2]. They come from the core-dump of the following
"thread_eight" program.
>How-To-Repeat:
Here's how I tried to get some information from gdb:
* Compile a threaded program (here, thread_eight.c [3])
* Start compiling a port. If the machine is completely idle, the
segfault is much harder to catch.
* Repeatedly launch the binary. It should eventually crash and
produce a core-dump.
* Then, launch gdb (or egdb) on it to get some information.
>Fix:
Unknown.
