            Bug ID: 31732
           Summary: ld.so is trapped in __libc_csu_init function, no
                    return or forward when load a normal ELF process
           Product: glibc
           Version: 2.30
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: dynamic-link
          Assignee: unassigned at sourceware dot org
          Reporter: liaozhicai at cigtech dot com
  Target Milestone: ---

context:
OS:Linux saturn2-sfu-eng 4.14.172.saturn2-sfu-r2.2.1.3 #1 Sat May 11 08:47:16
UTC 2024 mips GNU/Linux
arch:mips 32

   we employ kernel API fork/execv and try to load a ELF-format file with a
file name of MecMgr, as a result the main function is not entered occationally.
tracking the routine, it is found that the process is trapped in
__libc_csu_init function, no return or forward, and if add some printf-clauses
in the function showing us where is is when error occurred, the issue cann't be
reproduced again.
