Bug 257419: devel/rust-cbindgen: runaway build with infinite stack trace on
armv7
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D257419



--- Description ---
This port consistently fails to build in an armv7 FreeBSD 13.0 jail on an a=
rm64
FreeBSD 13.0 host.  The symptom is always the same: after processing a numb=
er
of files, the compiler crashes with a =E2=80=9Ccapacity overflow=E2=80=9D a=
nd then panics again
during the generation of the backtrace.  This somehow leads to an infinite
backtrace (see attached log where I truncated this backtrace to the first 1=
00
entries).

If left running, eventually Poudriere kills the port for being in a runaway
state, but not before generating several gigabytes of logs.

The attached log was generated on the quarterly branch, but I imagine it
applies to the main branch the same way.  Will test shortly.
