Re: [Sablevm-user] problem running sablevm for the first time...

[David <db...@cs...>]

Hi Dan,

Could you provide compilation options by running sablevm with the
--version option.

Also, provide your gcc version.

Without getting into the technical details, note that SableVM *inlined*
interpreter is highly dependent on both the CPU and the compiler version
used.

gcc 2.95 through 3.2 should be safe for the inlined on an intel CPU.
2.95 is safe for sure.
If you use 3.3, it should segfault... quite early, so don't
know if this is really the issue here.

Also, if not already done, try the slower switch interpreter:
configure option: --with-threading=3Dswitch
then, with the faster direct interpreter
--with-threading=3Ddirect
and also with debugging enabled:
--enable-debugging-features

To see if you get the same problem.


David
