Bug #34223 Assertion failed: (optp->var_type & 127) == 8, file .\my_getopt.c, line 830

Description:
got a debug assertion when setting a global variable, stack trace is:

mysqld-debug.exe!_NMSG_WRITE
mysqld-debug.exe!abort
mysqld-debug.exe!_wassert
mysqld-debug.exe!getopt_ull_limit_value

Version: '5.0.56-br20918-enterprise-gpl-debug'  socket: ''  port: 3307  MySQL Enterprise Server - Debug (GPL)
Assertion failed: (optp->var_type & 127) == 8, file .\my_getopt.c, line 830

How to repeat:
run a debug build of the server.  

mysqld-debug --port=3307 --console --skip-grant-tables --skip-name-resolve --innodb_buffer_pool_size=300M --innodb_flush_log_at_trx_commit=0

then:

set global innodb_commit_concurrency=0;

Thank you for the bug report. Verified on 64-bit OS:
