I wanted to trace this issue down to the root cause, but the Dart is quite
large project and I realy do not have time to isolate the code that triggers
this bug and fix it myself, so I just asked for help.

The core dump is quite useless as you can see:

Core was generated by `/bin/dart bin/run.dart'.
Program terminated with signal 6, Aborted.
#0  __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51
51  ../sysdeps/unix/sysv/linux/raise.c: No such file or directory.

I understand that you do not have such much time too, so lets close this case.

You obviously haven't read the page I just pointed you to.  See explicitly the
section "what we do not want".

The GCC, binutils and glibc were compiled using our toolchain builder
(https://bitbucket.org/bbsmartworx/tcbuilder), so you can find all information
about versions, options, etc. there.

The Dart SDK was built using instructions from here:
https://github.com/dart-lang/sdk/wiki/Building-Dart-SDK-for-ARM-processors. I
can provide final binary if you want to, but it is quite large.

This issue can be reproduced easily by executing the "dart" binary several
times.

I have tested it on embedded system with AM3352 CPU.

This is not a usable bug report.  We cannot provide a debugging service for
you, so you are going to have to narrow the problem down to something usable. 
See https://gcc.gnu.org/bugs/ for details of the information we would need.
