bus errror on sparc machines

Tal Tabakman-2
 Hi Guys,
 I get a bus error while running a sqlite based app on sparc machine (64
bits mode)

 here is my stack trace ,

 ffffffff74ab2dec  sqlite3_set_authorizer  + 505c
 ffffffff74adb8cc  sqlite3_vtab_config  + 99c0
 ffffffff74adc184  sqlite3_vtab_config  + a278
 ffffffff74add0f4  sqlite3_vtab_config  + b1e8
 ffffffff74ac536c  sqlite3_reset_auto_extension  + 38b4
 ffffffff74ac5628  sqlite3_reset_auto_extension  + 3b70
 ffffffff74ac5734  sqlite3_prepare  + 1c
 ffffffff74ac0f3c  sqlite3_exec  + b4

any idea what causes that ?
cheers
Tal

That stack looks impossible to me.  Are you sure you have the right symbol
file and that the stack is not corrupt.

Can you compile with -g and run the app in gdb until it crashes, so that we
can poke around and get better information?

FWIW, we do 100% branch coverage testing on sparc64 prior to every
release.  See http://www.sqlite.org/checklists/3071400#c12 for example.
