Segmentation fault on init (procd) when compiling with glibc and strip flag USE_MKLIBS

When compiling OpenWRT with glibc and by activating the USE_MKLIBS flag (for stripping the libraries) the platfaor got a kernel panic:

[    6.125785] init[1]: segfault at 7f3b67c25000 ip 00007f3b67c25047 sp 00007ffe7efe57e8 error 7 in[7f3b67c25000+6000]
[    6.145160] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
[    6.145160] 
[    6.157914] Kernel Offset: disabled
[    6.163101] Rebooting in 1 seconds..
[    7.168491] ACPI MEMORY or I/O RESET_REG.

So, there is a seg fault on init in the glibc.
When I removed the USE_MKLIBS flag the platform boots normally.

Is it a procd issue ?
or is it a glibc strpping issue ?
How can I investigate it ?
