[New-bugs-announce] [issue40226] Leak in tstate->interp->ceval.pending

[Stefan Krah]

New submission from Stefan Krah <stefan at bytereef.org>:

50e6e991781db761c496561a995541ca8d83ff87 causes or exposes a
leak. Possibly the leak was there before but showed up under
"still reachable".

Now it is "definitely lost", so tstate->interp->ceval.pending
needs to be cleaned up.


==11235== 32 bytes in 1 blocks are definitely lost in loss record 186 of 1,901
