[Tinycc-devel] Out of Bounds Write in end_macro

[Bugs SysSec]

Dear all,

While fuzzing tcc, an out of bounds write was found in the end_macro
function.


Attached are a file producing a crash when compiled and the output of
valgrind.


To reproduce, compile the attached input file with tcc

    tcc end_macro.c

The latest git version of tcc (commit
4b46e0ec630531fa85d742706272525bebea49d2) was tested.
