[Debian-med-packaging] Bug#861281: rnahybrid: FTBFS on armel

[Gianfranco Costamagna]

Hello,

the warning above is somewhat important
(too many nested loops), and this usually relates badly with
high optimization levels

gcc -DHAVE_CONFIG_H -I. -I.. -I/usr/include  -Wdate-time -D_FORTIFY_SOURCE=2 -g -O0 -fdebug-prefix-map=/home/locutusofborg/rnahybrid-2.1.2=. -fstack-protector-strong -Wformat -Werror=format-security -c -o energy.o energy.c


this made that file build in some seconds, by using -O0 optimization level.
Not sure, if you want to debug you can try to use -O1 (it seems to have the same issue as -O2), and disable features until you get the problematic one.
Manpage shows optimization levels and you can disable them with -fno-feature.

Not sure if armel might have any user for your tool, so probably removing it from armel is the best option
