Tried to gdb it but it failed with SIGSEGV immediately.

it seems address sanitizer is not initialized completely and prior it itself, application specific library trying to do address validation check for one of it’s thread memory allocation is causing this crash?
I am using glibc-2.35 and clang-14.0.6 compiler to build the application.
Seems it requires asan to initialize address sanitizer quickly prior to it’s use ? any specific patch introduced in latest compiler-rt package to address this issue? any insights plesae let me know?

Dear members,
in continuation to previous comment, i noticed above crash is not observed with clang-14.06 compiled same application that includes glibc-2.31 version.
From backtrace of crashed application, call stack shows crash in jemalloc api.
