Hi,
The preprocessed file:
http://people.linaro.org/~rikuvoipio/qmltextgenerator.ii.gz
With compile command line:
g++ -save-temps -c -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -fvisibility=hidden -fvisibility-inlines-hidden -Wall -W -D_REENTRANT -fPIC -o x.o qmltextgenerator.ii
Will take apparently forever (north of 1600min) on a debian native gcc. -O compiles instantly. Some bisecting for gcc optimization flags later, disabling strict aliasing allows instant build as well:
g++ -save-temps -c -g -O2 -fno-strict-aliasing -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -fvisibility=hidden -fvisibility-inlines-hidden -Wall -W -D_REENTRANT -fPIC -o x.o qmltextgenerator.ii
Happens with: gcc version 4.8.2 (Debian 4.8.2-19) and gcc version 4.9.0 20140405 (experimental) [trunk revision 209146] (Debian 20140405-1)
Linaro binary cross-compilers are compile the file fine with -O2.
do we do native gcc testing, or should it be just submitted upstream bugzilla?
