/*
   20051104-1.c from the execute part of the gcc torture suite.
 */

/*
   Optimization transformed 'if (cond) *ptr = 0;' into '*ptr = (cond) ? 0 : *ptr;'
   and thus wrote to literal string which gives undefined behavior
   or in the case of gcc a segmentation fault.
   The pointer being a plain char* and assigned a literal string is essential to the bug.
   Therefor warning 196 must be disabled.
