Hi,

I like this testing technique, and the test passes for me.

Except: if I put

	CC = cc -m32
	NO_OPENSSL = YesPlease
	NO_CURL = YesPlease

in config.mak (the first line to force 32-bit pointers, the others
to avoid some dependencies on libs that I don't have 32-bit versions
of), then the test fails for me:

 $ ./t6600-test-reach.sh -v -x -i
 [...]
 expecting success:
         cp commit-graph-full .git/objects/info/commit-graph &&
         run_and_check_trace2 can_all_from_reach_with_flag num_walked 19 input \
                 "test-tool reach can_all_from_reach"

 ++ cp commit-graph-full .git/objects/info/commit-graph
 ++ run_and_check_trace2 can_all_from_reach_with_flag num_walked 19 input 'test-tool reach can_all_from_r
 each'

 can_all_from_reach(X,Y):1
 ++ cat perf-log.txt
 ++ grep 'category:can_all_from_reach_with_flag key:num_walked value:19'
 error: last command exited with $?=1

 #                       "test-tool reach can_all_from_reach"
 #

When I cat perf-log.txt, I see

  ..category:can_all_from_reach_with_flag key:num_walked value:20

instead of the expected 19.

Known issue?

Thanks,
Jonathan
