>Description:

Running the test harness in sqlite3 fails with a bus error on sparc64:

Core was generated by `testfixture'.
Program terminated with signal 10, Bus error.

(gdb) list
38992     ** process of being overwritten.

38994     for(i=0; i<nOld; i++){
38995       MemPage *p = apCopy[i] = (MemPage*)aCopy[i];
38996       memcpy(p, apOld[i], sizeof(MemPage));
38997       p->aData = (void*)&p[1];
38998       memcpy(p->aData, apOld[i]->aData, pBt->pageSize);
38999     }

39001     /*
(gdb) print p
$1 = (MemPage *) 0x40f51ab4

4 byte alignement is not enough...
The code tries to ensure 8 byte alignment, but I'm not sure I follow the
full logic of the scratch allocator and cells:

  aCopy[0] = (u8*)&szCell[nMaxCells];

szCells is only 4byte aligned and a pointer to 16bit values, nMaxCells is 84.

>How-To-Repeat:

   cd /usr/pkgsrc/databases/sqlite3-tcl && make test

>Fix:
somebody please pick this up...
