Lindev:

I will not remove Lindev because I can not link .so library based on ConsInterp and Dev

+ Kernel.baseStack issue (preliminary description):
|
|
|
+ baseStack is upper border:
|
|
|
+ * of garbage collector stack scan range (see Kernel.MarkLocals)
|
|
|
+ * of TrapViewer stack show range (see Kernel.TrapHandler)
|
|
|
+ it is initialized in Kernel.INIT and initially points close to upper
|
|
|
+ border of library stack (because Kernel.INIT called from library
|
|
|
+ constructor, which executes close to upper border of library stack)
|
|
|
+ it can be changed in Kernel.Start to skip unnecessary stack addresses
|
|
|
+
|
|
|
+ if libBB.so exports procedure for calling from main program,
|
|
|
+ then it will be executed on main program stack, not on library
|
|
|
+ stack, at stack addresses higher than baseStack.
|
|
|
+ Thus, MarkLocals and TrapViewer will work incorrectly.
|
|
|
+ in this case, to solve problem, baseStack should be adjusted and
|
|
|
+ should point to stack on which this exported procedure executes
|
|
|
+ if necessary, this can be done using auxiliary module Kernel_so_init
