Sorry for big piece of code and attached files, but this problem is very hard to replay.

Also XDevCfg.h is need

C source duplicated (for more exact)

[Oleg N. Cher]

Admins, please rename ticket to "FATAL Compiler Internal Error"

[Philipp Klaus Krause]

I simplified the reproducer a bit and added a regression test in [r10454]. To reproduce the issue, disable the #define guard.

[Sergey Belyashov]

Test bug-2363.c has been enabled because bug looks to be already fixed.

[Erik Petrich]

Reopened because regression test still fails for ds390:
Internal error: validateOpType failed in OP_SYMBOL(IC_LEFT (ic)) @ .../src/ds390/gen.c:867: expected symbol, got null op

[Erik Petrich]

Also fixed for ds390 in [r11809]
