symbols with name length > 4096 bytes #12

Closed sgrignard closed 8 years ago

sgrignard commented 8 years ago

Hello. I'm using cv2pdb to generate pdb files for c++ programs compiled with gcc 4.9. When using boost libraries in my program I get symbols names which are so long that they exceed the 4096 bytes of the kMaxNameLen constant defined in symutil.h. Changing the constant to a bigger size (8192 for instance) allows cv2pdb to output the pdb file but I'm not sure of the consequences of such a modification. Is the 4096 bytes a limit of pdb files or can it be changed freely ?

Visual Studio only supports 4096-byte symbol names: https://msdn.microsoft.com/en-us/library/074af4b6.aspx Seems this might cause issues.

Ok so the right approach would be to truncate those names, I will have a look at it.

In the D compiler, the symbol for CodeView debug information is limited to 0xffd8 characters, so it seems there is a larger headroom.

I guess this should be fixed by https://github.com/rainers/cv2pdb/pull/13. Please reopen if the issue persists and provide an example binary.
