Description:
When built with the Sun compilers (cc: Forte Developer 7 C 5.4 2002/03/09), log_group_calc_lsn_offset fails at startup with an assertion failure:
offset <= 0xFFFFFFFF
It looks like its a compiler bug with respect to sign extension (if you read the generated code, its sign extending the constant to be -1LL)
How to repeat:

compile & run - fails on startup
