--- Comment #7 from Reimar Döffinger <k...@reimardoeffinger.de> ---
This seems to be a logic bug in the realloc_CEnt function that was never
adjusted for compressed symbol support.
alloc_CEnt has this logic:
if (fromC) {
// szB can be arbitrary
} else {
vg_assert(szB ==
CACHE_ENTRY_SIZE);
}
However realloc_CEnt does not have such a fromC argument and unconditionally
checks
vg_assert(szB >= CACHE_ENTRY_SIZE);
Shouldn't these simply be aligned in behaviour?
Unfortunately I can't share any examples, but I would greatly appreciate if
someone could check my logic and consider a patch based on that.
I think it requires a rather large binary with lots of debug symbols, as the
cache re-uses compressed entries last, and that is when this bug happens.
