Zoltan Herczeg <hzmes...@freemail.hu> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hzmes...@freemail.hu --- Comment #1 from Zoltan Herczeg <hzmes...@freemail.hu> --- I think this is a known side effect of the SSE2 optimization in PCRE-JIT. The optimized algorithm reads aligned 16 byte data packets which might cross the boundary of the input (subject) buffer, and valgrind reports this as an error. However this is a valid operation, since the read is aligned, so it can never cause a memory read error. Of course the algorithm ignores data outside of the input buffer boundaries. To confirm this please change the following line in pcre_jit_compile.c: if (sljit_x86_is_sse2_available()) to: if (false) and check whether the error disappears. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
