It might be that Patch v434 has introduced a Buffer Overflow which can cause people in range to crash. Full details have been sent in to the support as well as a possible fix.

Short hand Proof of Concept pseudo code

zz_mode(START);\r
NLATEXT[0] = ' pack_size ';\r
NLATEXT[1] = ' ZZ_BV_NONE ';\r
zz_begexpr[0] = ' #1332 ';\r
zz_begexpr[1] = ' 8.8.17.1147 ';\r
if ( zz_bufov_assertion ) {\r
err( eMsgd("action buffer overflow; size %d",ZZLEXBUFSIZE PATCH434 BV_TYPE));\r
