[Larceny-users] assertion failure in stats_start_timer

[Marco Maggi]

When running my test suite for POSIX
functions, I get an assertion failure
on "Sys/stats.c" line 283. The test
just forks a new process and exits:

| (let ((pid (fork)))
| (if (= 0 pid)
| (exit)
| #t)

it is the child who fails. It is a
bohrbug, but happens only when I
call EXIT after FORK, if I call
"execv()", or the other functions
like it, no failure happens.

i686-pc-linux-gnu, larceny-5886.

P.S. The other stuff seems to work
("errno" access and NULL arguments to
functions).

Well, you learn something new every day; I had never heard the term
"bohrbug", nor of the distinction between "bohrbug" and "heisenbug"
before, but there it is on wikipedia!
