Package: bup
Version: 0.24b-1.1
Severity: serious
Hi,
bup FTBFS on sparc:
https://buildd.debian.org/status/fetch.php?pkg=bup&arch=sparc&ver=0.24b-1.1&stamp=1313905299
The failure is reproducible on smetana.d.o. From what I can tell, it
crashes in lib/bup/t/tbloom.py:test_bloom, line 18 (b.add_idx(ix)),
specifically in the call to bloom_add().
Here's a disassembly of that function, the crash is at 0x111c

I'll try to look into it more tomorrow, but I suspect the cast in
bloom_set_bit4 is broken (assumes 32bit alignment for buf but is being
passed a char *).
Cheers,
Julien
