Re: gcc/cpp segfaulting on i386-9.99.17?

["John D. Baker" <jdbaker%consolidated.net@localhost>]

Trying to build gstreamer1 and at-spi2-core on i386-9.99.17 (gcc-7), the
gobject-intropsection stage fails when 'gcc' gets SIGSEGV (gstreamer1) or
'cpp' gets SIGSEGV (at-spi2-core).

Below is the failure from at-spi2-core as an example:

Curiously, everything works fine in netbsd-9/i386 and they currently have
the same GCC (7.4.0).


I seem to recall a number of messages about at-spi2-core or some such
in one of the mailing lists, but now see no trace of them.

Anyone else tried building gstreamer1 or at-spi2-core on i386-9.99.17?
