stacktrace_from_exception contains misleading assert-message

[Ukilele]

There is a BOOST_ASSERT_MSG here:

stacktrace/src/from_exception.cpp

Lines 236 to 238 in 39afcef

	sizeof(void*) == 4,
	"32bit platforms are unsupported with libc++ runtime padding reusage. "
	"Please report this issue to the library maintainters."

Isn't sizeof(void*) equal to 4 on 32bit platforms and 8 on 64bit platforms? The assert-message reads contrary to its condition, doesn't it? I ran into this assert on a 64bit platform and got confused, because it says "32bit platforms are unsupported [...]".

Ouch.

Many thanks for the bugreport, fixed in upstream
