Hi,
I opened a ticket on the openssl github, but was told to go to the vendors instead. https://github.com/openssl/openssl/issues/9187
I am experiencing this on Fedora 29, Fedora 30, and Xubuntu 19.04. CentOS7 does not exhibit this issue which runs openssl 1.0.2, nor does Debian 9.9 which runs openssl 1.1.0.
```
$ dpkg -l | grep 'ii openssl'
ii openssl 1.1.1b-1ubuntu2.1 amd64 Secure Sockets Layer toolkit - cryptographic utility
$ openssl version
OpenSSL 1.1.1b 26 Feb 2019
$ uname -a
Linux laptappy 5.0.0-16-generic #17-Ubuntu SMP Wed May 15 10:52:21 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
```
The issue I'm encountering is that openssl is unable to parse a specific certificate.
```
$ openssl x509 -in cert.127.pem -noout
unable to load certificate
$ cat cert.127.pem

If I format the certificate to have a line length of 64, openssl can parse the certificate just fine.
```
$ fold --spaces --width=64 cert.127.pem > cert.127.fixed.pem

The interesting thing is that openssl will parse hundreds of other certificates with the cert text on a single line. Here's an example of working certificate with a single line blob.
```
$ openssl x509 -in cert.152.pem -subject -fingerprint
subject=C = US, O = Internet Security Research Group, CN = ISRG Root X1
SHA1 Fingerprint=CA:BD:2A:79:A1:07:6A:31:F2:1D:25:36:35:CB:03:9D:43:29:A5:E8
$ cat cert.152.pem

Doing a comparison on the certs shows the following which is weird.
```
$ cmp -b cert.127.pem cert.127.fixed.pem
cert.127.pem cert.127.fixed.pem differ: byte 93, line 2 is 103 C 12 ^J
```
The ticket usptream acknowledges the issue. A fix has been included in newer versions which we're now shipping. I'll therefore mark the issue as Fix Released.
