I've added the attachment of the affected code. The cflags used to build it are as follows: -O3 -march=armv7-a -mtune=cortex-a9 -mfpu=neon -fgcse-after-reload -fipa-cp-clone -fpredictive-commoning -fsched-spec-load -funswitch-loops -ftree-loop-distribution -ftree-loop-linear -fvect-cost-model -fomit-frame-pointer -fstrict-aliasing -Wstrict-aliasing=3 -Werror=strict-aliasing -msoft-float -fpic -ffunction-sections -fdata-sections -funwind-tables -fstack-protector -Wa,--noexecstack -Werror=format-security -D_FORTIFY_SOURCE=1 -fno-short-enums -pipe. This occurs at any optimization level.
