Hi there, for the last 3~4 days (always running the latest of public amd64-current) firefox behaviour was kind of "unfamiliar" - regular crashes after a few minutes.
Starting firefox in a xterm gave me this: ~ $ firefox firefox:/usr/local/lib/libicuuc.so.12.0: /usr/local/lib/libicudata.so.12.0 : WARNING: symbol(icudt58_dat) size mismatch, relink your program 1489350944851 addons.update-checker WARN Update manifest for e10sroll...@mozilla.org did not contain an updates property 1489350944986 addons.update-checker WARN Update manifest for fire...@getpocket.com did not contain an updates property 1489350944998 addons.update-checker WARN Update manifest for webcom...@mozilla.org did not contain an updates property 1489350945009 addons.update-checker WARN Update manifest for aushel...@mozilla.org did not contain an updates property 1489350945022 addons.update-checker WARN Update manifest for {972ce4c6-7e08-4474-a285-3208198ce6fd} did not contain an updates property Assertion failure: addr == p, at /usr/obj/ports/firefox-52.0/firefox-52.0/js/src/jit/ProcessExecutableMemory.cpp:322 Segmentation fault (core dumped) Am I right supposing that the most likely answer will be "Wait for the next snap!"? :-) Best, STEFAN OpenBSD 6.1-beta (GENERIC.MP) #7: Sat Mar 11 18:32:03 MST 2017 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 17079074816 (16287MB) avail mem = 16556789760 (15789MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xec080 (35 entries) bios0: vendor American Megatrends Inc. version "1.03.06" date 06/25/2014 bios0: Notebook W65_67SZ acpi0 at bios0: rev 2 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP APIC FPDT ASF!
