src/tests/parse_rss fails on 32 bits systems (but not i386)

[paulgevers]

I tried to improve the test coverage in the Debian package of liferea and uploaded what I though had the required ingredients to experimental. However, on 32 bit architectures, the parse_rss test fails because of a miss-match in the time. i386 passes (but that has weird floating point precision if I recall correctly).

See the results here:

Hah... I like when tests uncover bugs. Will take some time to work on it though...

[lwindolf]

@paulgevers I have some hope that #1233 fixes the issue. As I have no multi-arch build setup prepared (missing time) I'd like to ask you if you can test whether this helps.

[paulgevers]

I'm pretty sure I applied the patch but had this during test builds on armel

Version 1.15.1 now fails on the official Debian releases mips64el and s390x due to

./memcheck.sh parse_html favicon parse_date social
ERROR: memcheck reports problems for 'parse_html'!
==382210== Conditional jump or move depends on uninitialised value(s)
ERROR: memcheck reports problems for 'favicon'!

==382231== Conditional jump or move depends on uninitialised value(s)

Of the unofficial releases, at least ppc64 is also affected.
