--- Comment #6 from Rich Felker <bugdal at aerifal dot cx> ---
Are there any actual cases where malloc failure is not checked? I reviewed
regcomp.c briefly and it seems the result is eventually (just not immediately)
checked before use. However, there are major leaks when malloc has failed,
since multiple results are checked together and no effort is made to free the
ones that did succeed.
