On my laptop, it's: ==28218== Thread 3: ==28218== Invalid read of size 1 ==28218== at 0x4009EB8: strlen (vg_replace_strmem.c:412) ==28218== by 0x7B875FBC: lstrlenA (string.c:194) ==28218== by 0x4B2665B: threadFunc1 (thread.c:223) ==28218== by 0x7BC87137: ???

This is expected according to the source code: 222 /* lstrlenA contains an exception handler so this makes sure exceptions work in threads */ 223 ok( lstrlenA( (char *)0xdeadbeef ) == 0, "lstrlenA: unexpected success\n " ); -- Do not reply to this email, post in Bugzilla using the above URL to reply.
