Hm... are there crashes around sweep_strings on platforms other
than MS-Windows?
Now I have two crash reports to make me worry about GC. Both are
irregular and looks hard to reproduce:
- this bug (crash in compact_small_strings, MS-Windows only (?))
- http://debbugs.gnu.org/cgi/bugreport.cgi?bug=16817#11 - crash
marking C stack, OSX-only (?)
These crashes may be originated by the same bug (probably irregular
heap corruption). It's known that GC-related crashes may be caused
by freeing fonts during gc_sweep; this is
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=16069, but it should
not affect MS-Windows and OSX (and hopefully I'll fix it soon).
On GNU/Linux, valgrind makes great job in finding memory-related
errors; if there are similar tools for other platforms, it would
be nice to try. And what about using GCC and (sorry RMS) LLVM
sanitizers?
