Re: FSVS on gentoo crashes
Here's the thread about technical information. The problem seems to be - running dir__enumerator - on a directory with a stat() size of 414 bytes, - but having ~21k of filenames (414 is # of entries including . ..), the initial size allocation is too low, so that in the loop all the arrays have to be resized several times - and then realloc() tells about the corrupted heap (on the 3rd or 4th reallocation of names). Strangely, a watchpoint in GDB gave realloc() as worst offender (changing the few bytes before *names); using MALLOC_CHECK_=2 and inserting mcheck() calls identified line 556, which is (in the modified sources) the line size=(size*19)/16+1 (or similar) as offender, which is clearly bogus ... unless the C compiler (gcc 4.2.2, IIRC) is bad. I've had a look at alloc_count and count, too; but once, while alloc_count==200 and count==174, the heap was reported corrupted after the names[count]=... line - while there should enough space be there, so I can't explain that. valgrind doesn't yet run on libc6=2.7. Changing the initial allocation to some big value makes FSVS run. 2.6.22 had some reported NFS issues ... but they'd have to scribble over user-space memory.
