I'm not sure if this is a bug or if I'm using an unsupported setup.
In case anyone runs into a similar problem, here's why my vim stopped work=
ing.
Package builder:
poudriere jail 12.2-RELEASE amd64
Package consumer running vim:
Ancient PC running 12.2-RELEASE amd64
The root cause of the problem is that the poudriere jail was built with
CPUTYPE=3Dznver1 instead of stock FreeBSD.
Initial symptoms: vim crashes with illegal instruction.
It turns out the crash is actually in libperl.so.5.32. Throwing gdb at per=
l:
Program received signal SIGILL, Illegal instruction.
0x00000008005ce435 in dtrace_dof_init ()
at /usr/src/cddl/contrib/opensolaris/lib/libdtrace/common/drti.c:138
138 if (dof->dofh_ident[DOF_ID_MAG0] !=3D DOF_MAG_MAG0 ||
Current instruction is:
=3D> 0x00000008005ce435 <+165>: vmovq (%rax),%xmm0
Turning off option DTRACE fixes perl. vim still crashes because ruby also =
uses
dtrace (port offers no option to disable dtrace).
Disabling RUBY in vim finally fixes the problem.
It seems /usr/lib/dtrace/drti.o from the poudriere jail is included in per=
l/
ruby. I'm not familiar with dtrace probes. So I'm not sure if there is a f=
ix
short of disabling dtrace or not mixing CPUTYPE.
