--- Comment #42 from Nish Aravamudan <[email protected]> --- (In reply to Giuseppe D'Angelo from comment #41) > Out of curiosity, do valgrind or even better an instrumented build (with > ASAN/UBSAN) report anything wrong? IIRC, no, but I think I may have found it (possibly, going to need to build a new PHP7.0 to test). The old split implementation did not use JIT, but the newer one (as of https://github.com/php/php-src/commit/92655be7cf10f7551ee1a1ae7ea0f1bdcfa2ca6b) does. There was an older commit (https://github.com/php/php-src/commit/376ab3b7873ca04142185d8c08dbb4c4be152474) that indicates "Nested PCRE calls may clobber extra->mark and it has to be reinitailized" which is quite symptomatic here ... Will see if adding the reinit fixes the problem. -- 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
