I am getting a SIGABRT when evaluating string objects in AOLserver 4.0 b6. The pseudocode is:
interp=Ns_GetConnInterp (Ns_GetConn ())
obj = Tcl_NewStringObj (utf8string, len)
Tcl_IncrRefCount (obj)
repeat a_few_times
Tcl_EvalObjEx (interp, obj, 0)
end
Tcl_DecrRefCount (obj) /* NOTE: this statement happens later, and in a different thread */
This sequence runs OK in a load test, but once AOLserver decides to get rid of a connection thread after load goes down, and run cleanup handlers, an invalid memory block appears, leading to ABRT. Am I doing something wrong? Crash debug info follows.
Thanks!
Alex
