Hi Przemek and All, After seeing reports on HMG Forum about hbmk2 failing on Win98, I verified it myself and there is indeed something wrong with MT mode on Win98 systems, and it's not directly related to compiler.
So hbmk2 was the test program I used, BCC 5.5 and MinGW 4.4.1 builds. Running hbmk2.exe without parameter, gave these results: (no console output appeared so it must be crashing in startup phase) --- HBMK2_BCC caused an invalid page fault in module HBMK2_BCC.EXE at 015f:00467a33. Registers: EAX=00000001 CS=015f EIP=00467a33 EFLGS=00010207 EBX=00651ce0 SS=0167 ESP=0064f93c EBP=0065193c ECX=00000000 DS=0167 ESI=8162b734 FS=241f EDX=c002ffe0 ES=0167 EDI=8162b8f8 GS=0000 Bytes at CS:EIP: 50 48 75 f6 8b 45 fc 81 c4 80 fb ff ff 53 56 57 Stack dump: --- --- HBMK2_MINGW caused an invalid page fault in module KERNEL32.DLL at 015f:bff9d62b.
