Segmentation fault when running Borland linker tlink32.exe #107
Description
I'm trying to compile applications with Borland C++ 5.2 via wibo. With my preliminary fix mentioned in #106 I can execute bcc32.exe (the compiler itself) but the linking fails due to a segmentation fault in tlink32.exe. It has a segmentation fault at 0x00401120 (EDX and EAX are both 0), the function seems to be GetTls (FS:[0x2c] would be thread local storage array pointer from what I can tell).
The disassembly is this:
**************************************************************
* FUNCTION *
**************************************************************
void * __stdcall ___System__GetTls(void)
void * EAX:4 <RETURN>
___System__GetTls
00401115 a1 5b d0 MOV EAX,[_tls_index]
42 00
0040111a 64 67 8b MOV EDX,dword ptr FS:[0x2c]
16 2c 00
00401120 8b 04 82 MOV EAX,dword ptr [EDX + EAX*0x4]
00401123 c3 RET
Any ideas why the TLS pointer could be NULL?
Reproduce:
./wibo -D Borland/BC5/BIN/tlink32.exe
Output (tested on macos sonoma via Rosetta and linux x64 VM):
