Subject: [PATCH 01/18] Fix latent quote char bug in generic_printstr
Date: Wed, 16 Feb 2022 06:55:01 -0700 [thread overview]
Message-ID: <20220216135518.3162480-2-tom@tromey.com> (raw)
In-Reply-To: <20220216135518.3162480-1-tom@tromey.com>
generic_printstr prints an empty string like:
fputs_filtered ("\"\"", stream);
However, this seems wrong to me if the quote character is something
other than double quote. This patch fixes this latent bug, though I'm
not sure how to test it -- I don't know Fortran and in my experiment I
was unable to make a zero-length Fortran string.
