There are now reports, that this bug is not strictly related to 32 bit architecture (though always with compiled rules).
Since there have been offers for further testing: One data point is to collect details about systems, CPU architecture, instruction set used for compiling, versions (OS, kernel, compiler, re2c, Perl) and patch- level. Another might be to reproduce the issue, and get a minimal test-case. For that, can you reproduce the problem with trivial REs for the three __PILL_PRICE_x sub-rules? Can you reproduce the problem by keeping (a renamed copy of) the original sub-rules and tflags, using a simple meta rule? Are two of them sufficient? Or even one? -- char *t="\10pse\0r\0dtu\0.@ghno\x4e\xc8\x79\xf4\xab\x51\x8a\x10\xf4\xf4\xc4"; main(){ char h,m=h=*t++,*x=t+2*h,c,i,l=*x,s=0; for (i=0;i<l;i++){ i%8? c<<=1: (c=*++x); c&128 && (s+=h); if (!(h>>=1)||!t[s+h]){ putchar(t[s]);h=m;s=0; }}}
