Description (last modified by )
Hardware + software
- Sun T5240 with two T2+ UltraSPARC processors
- 2 CPUS = 16 cores = 128 hardware threads
- 1167 MHz
- 32 GB RAM
- Solaris 10 update 7 (5/09)
- sage-4.5.rc0 with:
- gcc 4.4.1 configured to use the Sun linker and Sun assembler.
The problem
John Palmieri built Sage and run the long doctests. After inspecting Joh's ptestlong.log, I find the following test fails, even if run from the command line, and with SAGE_TIMEOUT_LONG increased to 10,000 seconds, which ensures there are no timeouts (around 3600 seconds should be sufficient on 't2.math' for SAGE_TIMEOUT_LONG)
sage -t -long "devel/sage/sage/libs/galrep/wrapper.pyx" ------------------------------------------------------------ Unhandled SIGBUS: A bus error occurred in Sage. This probably occurred because a *compiled* component of Sage has a bug in it (typically accessing invalid memory) or is not properly wrapped with _sig_on, _sig_off. You might want to run Sage under gdb with 'sage -gdb' to debug this. Sage will now terminate (sorry). ------------------------------------------------------------ [18.0 s] ---------------------------------------------------------------------- The following tests failed: sage -t -long "devel/sage/sage/libs/galrep/wrapper.pyx" Total time for all tests: 18.0 seconds

When I reran the test using "sage -t -long -verbose ...", I got this:

- Milestone changed from sage-4.5.2 to sage-4.5
- Resolution set to fixed
- Status changed from new to closed
This can be closed, it was a patch (#8617) new to the 4.5 series which caused this problem, and Robert removed it before releasing 4.5. So this fortunately never appeared in a Sage release.
Using sage-4.5.1 on a Sun Blade 1000 (dual 900 MHz UltraSPARC III+, 2 GB RAM), I get:
