be done on other platforms, too. Since I can't test those, that'll
wait until after 5.0.
Since 5.0alpha7:
- Fixed threadlibs.c for linux threads. -DUSE_LD_WRAP was broken and
-ldl was omitted. Fixed Linux stack finding code to handle
-DUSE_LD_WRAP correctly.
- Added MSWIN32 exception handler around marker, so that the collector
can recover from root segments that are unmapped during the collection.
This caused occasional failures under Windows 98, and may also be
an issue under Windows NT/2000.
To do:
- Integrate Linux/SPARC fixes.
- Very large root set sizes (> 16 MB or so) could cause the collector
to abort with an unexpected mark stack overflow. (Thanks again to
Peter Chubb.) NOT YET FIXED. Workaround is to increase the initial
