[Bug 259799] devel/rust-cbindgen: armv6: build using "make" fails, using "cargo build --release -j 1" works

(In reply to Mark Millard from comment #36)

The try in comment 36 was under main-CA7 jail. I tried under
the 13_0R-CA7 jail (so: 13.0-RELEASE-p5 world) (without rustc
having been stripped but having no debug information) and the
failure was more like before but it did stop

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report:
https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.56.0 running on armv7-unknown-freebsd

note: compiler flags: -C embed-bitcode=no -C debuginfo=2 -C linker=cc -C
target-cpu=cortex-a7 -C link-arg=-fstack-protector-strong --crate-type lib

note: some of the compiler flags provided by cargo are hidden

(signal: 5, SIGTRAP: trace/breakpoint trap)
*** Error code 101


Notabily in this context it reported SIGTRAP instead of the SIGSEGV that
main-CA7
reported.

Also notable is that the capacity-overflow happened during the attempt to
do a backtrace that had already been initiated: Nested problems? (Possibly
SIGSEGV was first?)
