Describe the bug
cuDF throws cudaErrorIllegalAddress: an illegal memory access was encountered when attempting to replace an input using a regex containing a repetition that could possibly match zero results, followed by a string anchor $. The error seems to only happens when the character preceding the repetition does not appear in the input.

Steps/Code to reproduce bug

>>> import cudf
>>> cudf.Series(['b']).str.replace('a?$', '#', regex=True)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/antchang/miniconda3/lib/python3.9/site-packages/cudf/core/column/string.py", line 931, in replace
    libstrings.replace_re(
  File "cudf/_lib/strings/replace_re.pyx", line 41, in cudf._lib.strings.replace_re.replace_re
RuntimeError: for_each: failed to synchronize: cudaErrorIllegalAddress: an illegal memory access was encountered

The error does not happen if the character before the repetition is in the input:

>>> cudf.Series(['a']).str.replace('a?$', '#', regex=True)
0    ##
dtype: object

The same error happens for any repetitions that could possibly match zero results:

>>> cudf.Series(['b']).str.replace('a*$', '#', regex=True)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/antchang/miniconda3/lib/python3.9/site-packages/cudf/core/column/string.py", line 931, in replace
    libstrings.replace_re(
  File "cudf/_lib/strings/replace_re.pyx", line 41, in cudf._lib.strings.replace_re.replace_re
RuntimeError: for_each: failed to synchronize: cudaErrorIllegalAddress: an illegal memory access was encountered
>>> cudf.Series(['b']).str.replace('a{0,5}$', '#', regex=True)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/antchang/miniconda3/lib/python3.9/site-packages/cudf/core/column/string.py", line 931, in replace
    libstrings.replace_re(
  File "cudf/_lib/strings/replace_re.pyx", line 41, in cudf._lib.strings.replace_re.replace_re
RuntimeError: for_each: failed to synchronize: cudaErrorIllegalAddress: an illegal memory access was encountered

However, the same case works for searching

>>> cudf.Series(['b']).str.contains('a?$', regex=True)
0    True
dtype: bool

Expected behavior
I expect the replace operation to complete with no error.

I believe this is fixed now in #10760 which is included in 22.06.

>>> cudf.Series(['b']).str.replace('a?$', '#', regex=True)
0    b#
dtype: object
>>> cudf.Series(['a']).str.replace('a?$', '#', regex=True)
0    ##
dtype: object
>>> cudf.Series(['b']).str.replace('a*$', '#', regex=True)
0    b#
dtype: object
>>> cudf.Series(['b']).str.replace('a{0,5}$', '#', regex=True)
0    b#
dtype: object
>>> cudf.Series(['b']).str.contains('a?$', regex=True)
0    True
dtype: bool
