Bug ID: 52264
Summary: Consider increasing the size of the static
symbolization buffer in sanitizer_common
Assignee: unassignedbugs at nondot.org
Reporter: andrew.c.morrow at gmail.com
CC: llvm-bugs at lists.llvm.org
It appears that there are some 16K static buffers for the symbolizer:
I have recently encountered some events where it appears that one or more of
these buffers is not sufficient when symbolizing sanitizer failures, leading to
==4094==WARNING: Symbolizer buffer too small
Would it be possible to expand these to something larger, maybe 1M? While no
fixed-sized buffer can handle everything, 16K feels very conservative.
