C source code



I just tried to compile the package freetds-0.91-5

on gcc-4.8 trunk dated 20121212 on an AMD x86_64 box.



The compiler said



convert.c: In function 'string_to_numeric':

convert.c:1939:1: internal compiler error: in remove_redundant_iv_tests, at

tree-ssa-loop-ivcanon.c:559

 string_to_numeric(const char *instr, const char *pend, CONV_RESULT * cr)
