Description
These three nightly tests failed with SIGSEGVs in _int_malloc() on linux-amd64:

nsk/jdi/ReferenceType/allLineLocations/alllinelocations002
nsk/jdi/ThreadGroupReference/threadGroups/threadgroups001
nsk/jdi/VirtualMachine/redefineClasses/redefineclasses030

Attached is the log and hs_err_pid file for one of the tests, threadgroups001.
Comments
Seems like the same issue as JDK-8004285, which contains more information. Closing this one as a duplicate

Zhengyu tried to reproduce on chinette, but neither this nor 8003843 failed. A note: chinette has libc-2.11.1 and sqe system has libc-2.11.3

Failure mode is very similar to JDK-8003843. VM not initialized. SEGV in C library code. No stack traces. JDI

Appears to be a crash during VM initialization. Lack of stack trace is curious. I would suspect a possible mismatch between JDI expectations and VM internals - possibly related to NMT ?
