   > @masayuki2009 how the crash is reproduced? Maybe we need to create an 
issue to investigate it?

   The crash can be reproduced with my branch (imx6-netknsh) which is still 
under testing if it is linked with thumb-based libraries plus arm_elf.c 
supporting thumb relocation. Actually, it crashed  inside __aeabi_xxx which is 
a gcc helper function. I'm still not sure why the crash happens. I suspect 
there still be a potential bug in context switching but this PR is just a 
workaround to avoid such a crash.

   OK, it should be isolated for armv7-a.
