Re: Need for scm_remember_upto_here_* in guile-2.0

[Ludovic Courtès]

Hello,

In practice scm_remember_upto_here_* is useless with libgc, since libgc
also tracks pointers in registers.

scm_gc_free should not be used, unless you really know what you are
doing (it must be passed a valid pointer to the beginning of a
GC-allocated area) and have a real need for it (like you know you’re
freeing a big memory region and waiting for it to be collected would be
impractical.)
