[DragonFlyBSD - Bug #3319] (Closed) setproctitle() calls can change effect of later setproctitle() calls

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #3319 has been updated by swildner.

Status changed from New to Closed

Turns out that a format beginning with '-' stopped working properly after the 10th call to setproctitle(). DragonFly switches to a faster way after 10 calls and that didn't handle the '-' properly.

Fixed in https://gitweb.dragonflybsd.org/dragonfly.git/commitdiff/b866b1dac9e41035fffd5f4cec3b0a24a95916b6

----------------------------------------
The final setproctitle() call in the attached code results in different outputs from ps depending on the whether the earlier setproctitle() calls are present.

$ cc 19894.c && ./a.out 
x (a.out)
$ cc -DMANY 19894.c && ./a.out 
a.out: -x (a.out)
$ uname -a

This came up from new perl tests failing on DragonflyBSD.
