How far are you going back in the bisection effort? You may be earlier than
the point at which GCC on AIX generated stab strings continuation lines. At
worst you manually can apply the continuation code from gcc/xcoffout.h
/* XCOFF32 maximum length is 64K; XLC limits to 16K. */
#define DBX_CONTIN_LENGTH 16384
/* XLC uses '?' as continuation character. */
#define DBX_CONTIN_CHAR '?'
