Only I get an error

[Ivan C.]

Another member of my team, with the same version of PL/SQL Developer (12.0.7.1837, 64-bit), and similar machine (Windows 10 Pro), connecting to the same DB (Oracle Enterprise Edition Release 12.2.0.1.0 - 64bit, on Linux) is able to compile the code just fine, while I'm getting an error.

I tried restarting PSD and Windows, but the error persists.

The error I'm getting is

PLS-00707: unsupported construct or internal error [2620]

The same code compiles fine in SQL*Plus.

I don't know where to begin to research why it fails in (only my instance of) PL/SQL Developer.

Please help.

Are you both also using the same version of Oracle Client?

In PL/SQL Developer go to Help->Support Info, scroll down to where it says "Using" in red, and compare the values.

Using
  Home: OraClient12Home1
  DLL: C:\app\client\<username>\product.1.0\client_1\bin\oci.dll
  OCI: version 12.1  (12.1.0.1.0)
  Oracle Database 12c Enterprise Edition Release 12.2.0.1.0

Except for the (obviously) exactly identical.
Thank you for your suggestion. Was worth a shot.

Could it be related to PL/SQL Developer settings? I would try running with default settings by temporarily renaming the preferences directory to something else.

My settings are at C:\Users\\AppData\Roaming\PLSQL Developer 12
