This caused occasional failures under Windows 98, and may also be
|
||||
an issue under Windows NT/2000.
|
||||
|
||||
Since 5.0
|
||||
- Fixed a gc.h header bug which showed up under Irix. (Thanks to
|
||||
Dan Sullivan.)
|
||||
- Fixed a typo in GC_double_descr in typd_mlc.c not getting traced correctly.
|
||||
This probably could result in objects described by array descriptors not
|
||||
getting traced correctly. (Thanks to Ben Hutchings for pointing this out.)
|
||||
- The block nearly full tests in reclaim.c were not correct for 64 bit
|
||||
environments. This could result in unnecessary heap growth under unlikely
|
||||
conditions.
|
||||
- Removed use of CLEAR_DOUBLE from generic reclaim code, since odd sizes
|
||||
could occur.
|
||||
|
||||
To do:
|
||||
- Integrate Linux/SPARC fixes.
|
||||
- Very large root set sizes (> 16 MB or so) could cause the collector
