Hello,
Using a recent trunk version of fossil, built with gcc on Solaris
10 on an UltraSPARC system, I get a bus error from "fossil new":
$ ./fossil new t.fossil
Bus Error (core dumped)
I'm unable to replicate the problem. The latest Fossil works fine for
me on Solaris and SPARC. But see my question below....
Bummer, I'd hoped it would be reproducible. (I wonder what is different
about my system.)
Here is some system info, just in case:
$ uname -a
SunOS v245 5.10 Generic_147147-26 sun4u sparc SUNW,Sun-Fire-V245
$ cat /etc/release

Can you use the debugger to give us the value of &pWInfo->sMaskSet
please? Perhaps this is an alignment problem.
Adding an extra line for debugging (and compiling with "-O0" so it
doesn't disappear) suggests the issue may be with pNew:
pNew->iTab = iTab;
+ pNew->maskSelf = 1;
pNew->maskSelf = getMask(&pWInfo->sMaskSet, pItem->iCursor);
